Data Scientist at Mercor - INDIA [$27-$32]

Hi everyone!

I’m sharing a job opportunity through Mercor. Just to clarify, I don’t work for Mercor as an employee or as part of their hiring team, but I do work as a contractor on other Mercor projects. I’m only sharing this opportunity in case it’s useful to anyone.

This is a general opportunity that may be a good fit for people looking for remote work, flexible projects, or international projects.

Rates depends on your experience.

If you’re interested, I recommend reviewing the details directly through the link.

I also created this tool on Claude so you can create a CV that fits perfect the RTS on Mercor.

Good luck to anyone who applies!

Working with AI - Honest Review

TL;DR
Most projects are about training and evaluating LLMs or LLM prompts.

It pays really well, but you need English skills and at least some work experience to get the better rates.

You are probably helping train the LLM that may replace you, but if you do not do it, someone else will, so you might as well make money from it.

My experience
I was going through a really difficult time in my career and had to take time off because of workplace bullying at my previous job. I already knew that once I came back, I was going to be fired.

I was really scared of losing my income, especially since I was responsible for about 80% of all the money coming into my household.

Out of desperation, I started looking for jobs and freelance work, since English is my second language and foreign currencies are much stronger than my local one.

Because I work in Data, LinkedIn started showing me a lot of openings on AI platforms like DataAnnotator, Mercor, Outlier, and others.

I decided to try one of them, and even though the idea seemed interesting, I was pretty afraid it might be a scam or something like that.

I picked one of these platforms and started doing the AI interviews.

At first, it felt a little weird talking to an AI. But after a few interviews, I noticed that the experience was actually much better than what I had with a lot of HR recruiters.

The downside is that on most of these platforms, there is no formal feedback, so you do not really have a good way of knowing whether you did well or badly.

Some people I have seen spend months without landing anything, while others get work pretty quickly.

I have to admit I got a little lucky, because in my second week after signing up on the platform, I got 3 offers.

Contract 1: $20/hour

Contract 2: $30/hour

Contract 3: $50/hour

The first two did not work out. Even though I had accepted them on the platform, the contracts were paused or canceled before they even started.

Luckily for me, the third one was the one that actually happened.

I was able to work on it, but I did not put in much effort at first because I was still afraid of working and not getting paid.

Some platforms pay weekly and others every two weeks through Stripe, which is the most common, PayPal, or Wise.

On payday, it finally hit me that it was legit, even though a lot of people say it is a scam.

The problem is that these projects are usually short. Most of them last only 1 to 2 weeks.

One very important thing I noticed is this: networking matters.

If you join a project and do well, project leads will ask whether you can join another one or help with a project that is behind schedule.

That is how I got my second project. In that one, since I was already familiar with the platform and no longer afraid it was a scam, I worked A LOT.

I managed to make $2,100 in 5 days on a project I was invited to because it was behind schedule.

Later, I got one more project the same way, by being recommended from inside another project.

That money saved me, because I had been without pay for many months. Right now, I am actively working on two platforms and improving my technical skills a bit so I can try to get offers paying $100/hour or more.

Pros and cons, in my opinion

Pros:

  • It pays in dollars Rates can go above $80/hour for people with more than 4 years of experience or a postgraduate degree.
  • Variety of fields This really surprised me. I thought it would only be about tech, but there are projects for literally every field you can imagine. That makes sense, since LLMs need to be trained across all areas of knowledge.
  • Flexibility Most projects require a minimum workload of 10 hours per week, and you are not punished for not working more than that. You can work any day and at any time. It is possible to combine this with a regular full-time job.
  • Task-based projects You usually just need to complete a task and submit it. Some tasks have a maximum time of 10 minutes, while others give you up to 1 hour and 30 minutes, especially STEM projects.
  • Meritocracy If you do a good job, your chances of getting new projects without constantly applying are VERY high.
  • Realistically, I worked on 4 projects on this first platform, not counting the canceled contracts, but all of them came from the same initial project where I got referrals.
  • Reusable interviews and tests You usually only do an interview or test once, and then you can apply for multiple roles without having to repeat the whole process.
  • AI interviews This may be controversial, but for me, they really can evaluate your knowledge without the bias, laziness, or bad attitude that we often see from many human recruiters.

Cons:

  • Lack of transparency in interview results Most platforms do not give feedback. They let you retake interviews a limited number of times and say that your best result is the one that counts, but there is no actual feedback.
  • Bad matching or slow placement into projects Each platform has its own way of scoring candidates based on profile, interviews, and assessments.
  • Some platforms, like the one in my story, do this very poorly. A lot of the time, you may have interdisciplinary skills but still be prioritized for only one area.
  • For example, if you are a developer with an engineering background, you will probably be prioritized for dev roles and deprioritized for engineering roles, even though you could do STEM projects in that field too.
  • Work experience versus academic background If you do not have much work experience in your field, meaning 2+ years, or you do not have a postgraduate degree, the hourly rates tend to be lower, around $15 to $30/hour.
  • Lack of predictability You cannot really quit your regular job, because you might get a project that pays well but only lasts 2 weeks, and then go a long time without getting anything new.
  • You need to know English There is no way around this. The interviews are in English, and the conversations are in English.

Let me help you improve your CV (Using Mercor’s Own Guides) - v2

So,

i have previously made this post where i share a ChatGPT agent to help you improve your CV.

I've improved the tool I shared earlier: I created a Claude Project that helps you build your CV/PROFILE from scratch and exports it as a DOCX and PDF, ready to upload directly to your Mercor profile (or any other platform).

Since Claude doesn't let you share projects the way OpenAI does, I created a GitHub repository with a step-by-step guide to build the tool yourself.

What I learned while building this:

Mercor takes into account every change you make to your profile, but CV parsing is the most important piece. The combination that made the biggest difference for me: getting the CV parsed correctly + updating your Work Preferences to include only the domains you actually have background in.

One thing that's not obvious: Mercor prioritizes your first 5 skills when ranking your profile. Everything after that matters less. So be intentional, put the skills most relevant to the roles you're targeting in those top 5 spots, both in your CV and in your profile settings.

My advice: tell Claude your priorities upfront. Share your main domain and a secondary one if you have it (mine were Data Science and STEM). The more specific you are, the better the output it changes how skills are ordered, how the summary is written, and which projects get highlighted.

Feel free to use it and adapt it however works best for you.

Github link of the project: https://github.com/mbalmeidaj/cv-optimizer-claude/tree/main

Edit:

After the ChatGPT post that i made earlier, that were 3 people that reached me. Here's one:

I don't think i have permission to show the other messages but, i really felt good to see someone in real life the actually got something from the tool :)

My two cents on rejections

Edit:

“Timeout” is my inferred category for automated rejections that seem to happen when an application stays stuck in one stage of the process for X days without being prioritized or moved forward, eventually triggering an auto-rejection configured by the platform/recruiter.

TL;DR

I have nothing better to do in my life so i found out:

I clearly have nothing better to do with my life, so I analyzed my own rejection data:

  1. 71.6% of my rejections came from timeout.
  2. Many rejection emails arrived in batches, which makes the process look automated.
  3. Timeout was common even in listings that were still close to my background.
  4. Domain mismatch mattered, but much less than I expected.
  5. My main takeaway is that Mercor seems to reject a lot of applications through timeout, not just through actual profile review (but this is an assumption)
  6. Maybe the listings are being filled out before reaching your profile, idk

Context

As a data scientist (and also a physicist), i always need to understand how and why things happen.
I see many posts here about rejections, and i get rejections email every single time.
Since we don't have many information about our assessments results or a formal feedback on applications, i tried to understand patterns to figure why i'm being reject, with two hipotesis:

  1. I'm being rejected because of some automatic timeout
  2. I'm being rejected because i'm applying to listings outside my domain

After looking at my own available application information, my assessments, and my rejection emails, these were my main findings:

  • The strongest pattern by far was timeout.
    • Time out patterns i found : 7 and 14 days.
  • Most of my rejections were associated with timeout, so this was not a marginal reason, it was the dominant one.
  • Rejection emails also often arrived in batches, with several rejections coming at the same time for listings i had applied to in the same period.
  • This batch behavior makes timeout look much more like an automated pipeline process than an individual manual review of each case.

About domain fit:

  • I used Data Analysis as my main domain.
  • I treated Life, Physical, and Social Science as a secondary domain, since it is also close to my background.
  • Yes, part of my rejected applications were outside those areas.
  • So domain mismatch is probably a real factor in some cases.

But the main point is this:

  • Even when i look at applications that were still reasonably close to my profile, timeout still appears a lot.
  • So the data does not support the idea that i was rejected mainly because i was applying to completely wrong listings.
  • It looks much more like this: applying outside domain increases rejection risk, but timeout is still the main mechanism behind most rejections.

So, my conclusion is:

  • domain mismatch matters
  • timeout matters more
  • and a meaningful part of the rejection flow seems to be automated

This is not a complaint, just a datapoint from my own case.

I think Mercor should provide better transparency on whether a rejection came from actual review, project closure, or timeout, because these are very different things for candidates trying to improve their application strategy.

Also should consider me for data science and analysis positions, just saying :P

Sempre detestei meu trabalho. Porém, sempre fui bom em automatizar tudo que eu faço para que minha carga de trabalho diminuisse e eu pudesse fazer outras coisas durante o horario do meu trampo.

Porém, fui sacaneado na minha antiga empresa e passei um tempo sem trabalhar e quando voltei, fui demitido.

Consegui me realocar porque eu trabalho com algo que é bem escasso no mercado, porém nesse periodo que fiquei sem trabalhar, tive contato com alguns sites de empregos com IA que me fez entrar em projetos ganhando 50 dol/hora , podendo trabalhar 10-30 horas por projeto.

Esse método de ganhar dinheiro me deixou "viciado". Antes, no CLT, meu esforço e tempo era recompensado com mais trabalho e sem aumento salarial.

Com esses projetos, eu ganho por hora trabalhada e muitas vezes eu consigo automatizar o trampo de 5 horas para ser feito em 2 horas e só deixo meu PC ligado para nao ficar registrar como IDLE.

Agora, estou em 4 projetos ( 2 ativos e 2 pausados).

Um paga 50 dol a hora , o outro paga 65 dol a hora, e pra variar, ainda tenho meu CLT.

Estou tentando conciliar isso, mas por enquanto, estou acordando 8h da manha e ficando até 20-21h trabalhando. Sempre que tenho tempo livre no meu trabalho, eu inicio o relogio em projetos.

Sinto que não vou aguentar fazer isso por muito tempo, porém, ao mesmo tempo, sinto que essa é uma oportunidade grande para eu fazer o maximo de dinheiro possível para parar de trabalhar.

Como vocês fariam para se organizar e conciliar essa rotina?
