I got an interview invitation for a Machine Learning Engineer role at a FAANG company. There are two issues. I am not an MLE, so preparing for it feels nearly impossible. Also, I have never even interviewed for an MLE interview, let alone at FAANG.

I am currently a Data Scientist and have been interviewing, so I feel good about my preparation for DS roles. Can I tell the recruiter that I believe I am a better fit for a DS role than MLE? Do you have any other suggestions?

I did a physical onsite recently where they asked me to travel to their office, about 1.5 hours each way. The interviewers were nice and the interviews went pretty well, so I was hoping to hear back from them. The opposite happened. It has been two weeks since the onsite and I have not heard anything.
The recruiter was very polite before the onsite, but after it they completely stopped responding.

I had to take a day off work and make arrangements in my personal life, and the company cannot even bother to send a rejection email? I have never had a job search this difficult before.
