It's friday. Interview is on monday. It's not even my dream job, it's a backup option. But my body has decided we are going to spend the entire weekend being sick about it.

Last night I couldn't fall asleep until like 4am. My brain just kept running through the worst case scenarios. Me freezing. Me crying. Me forgetting my own name.

I know I'll probably do fine. I always do fine, ish. But the buildup is the part that wrecks me. By the time I'm actually in the interview I am running on 4 hours of sleep across 3 nights and I forget basic things.

How do you guys get through the days before? I don't need productivity tips, I need just. Actual sleep advice for anxiety brains. Melatonin doesn't touch this.

Instagram lets you add like 10 accounts on one phone, which is fine at first, but once you go past that it gets kinda annoying to manage everything. Some people switch to using multiple phones but that gets tiring fast, especially if you’re working with other people. I’ve seen others just keep each account in its own setup instead, like using stuff such as GeeLark so things don’t overlap too much. As long as you’re not rushing actions and each account kinda does its own thing, it usually feels more manageable. Also way easier for teams since you’re not passing devices around all the time. Have you found a setup that actually works without getting messy?

I’m a backend engineer with 5 years of experience. At work I do system design stuff all the time. Schema planning, service boundaries, tradeoffs, architecture calls, all that. A while back I even worked on a project where I mapped out a data model with a client, and it held up well. Barely needed migrations after, queries stayed clean, team was happy.

Then I got into a system design interview for a company I actually wanted and completely fumbled it. The feedback was basically that I didn’t explain tradeoffs clearly enough.

That part really annoyed me because it’s not like I don’t think about tradeoffs at work. I do. But at work it’s never this weird one-shot thing where someone throws a prompt at you and expects a clean 45-minute performance. Usually it’s messy. You ask questions, sketch something, go down one path, back up, talk it through with people, adjust.

In interviews, none of that seems to count. You’re supposed to sound structured from minute one. I’ve been trying to get better at that part by doing mock system design with a friend. One of us plays interviewer, the other gets pushed on every decision. We’ve been using one of those shared mock setups too just to keep it from turning into a casual chat and to get nudged when we both get stuck. Still, the whole thing feels off to me. The skill that helps me do the job and the skill that helps me pass the interview do not feel like the same skill.

Anyone else feel this gap?
