I had a call with the recruiter, who explained the company, the opportunity, and the type of candidate they were seeking. I then received an email outlining the first interview steps: mutual introduction and initial questions, designing a data labeling pipeline, and a Q&A about the team and company. I'm fully prepared for the interview. However, they rescheduled it to 45 minutes later without confirming if it worked for me, so I had to rearrange my other meetings. I waited 15 minutes for the interviewer to show up. After introductions, we moved on to the data labeling pipeline, and I received positive feedback on my approach. This part took about 10-15 minutes. However, the interviewer then asked multiple personal questions that are illegal in the US. Throughout these inappropriate questions, I was repeatedly asked if I could stay longer than the scheduled time, which I did. The interview, scheduled for one hour, ran over by 45 minutes. Despite this, I received a rejection letter citing my technical knowledge as the reason, which is odd given that this part only took 10-15 minutes of the 1 hour and 45-minute interview. I will have my employment attorney contact Toloka about their illegal interview questions and processes. I write this to warn others not to waste their time with a company that conducts unprofessional interviews and rejects candidates based on illegal questions.

Very straight forward, not complicated at all. Hiring manager round, technical round, then team manager round. Got to final round with almost a guarantee of hiring but then was ghosted.
