I applied online.

Spoke with a recruiter, who was nice but had limited knowledge of the role. The job was for a ML Performance Engineering position to improve training performance of LLMs. Then had a technical interview.

The technical interview didn't go well for a variety of reasons:

• The question was a twist on an algorithms question, but a string-based one, which seems completely irrelevant for the job (what GPU engineer works with strings...?)
• The more frustrating part was the interviewer not being able to clearly answer my questions about their coding question
• He also kept changing the question away from what was written when I had the correct solution to the written question almost completed

It was a C++ interview, and the interviewer said he is not that familiar with C++, which was also very disappointing.

I messed up my solution to a certain extent, so I agree with not putting me through, but the experience overall was very bad and disappointing due to the lack of clarity by the interviewer.

Cannot disclose due to NDA.
