xAI Machine Learning Engineer interview questions

The technical round hit hard with a question to implement multi-head self-attention from scratch in PyTorch. I felt the pressure as I explained the time and memory complexity, but the real surprise came when I recalled a similar problem I had practiced on PracHub just days before. Following that, I had a casual chat about the role and my experience, and then wrapped up with a behavioral interview. Once everything was done, I received an offer, which I gladly accepted. Overall, a challenging yet rewarding experience.
