Interview questions [1]
Question 1
they were asking about coding optimization although I applied for a research scientist position, not a software engineer related work
The interview process is quite general and now after Covid, it includes initial screening, and if passed, you will need to do a presentation, then go to full rounds including all types of interviews
First you will have a phone interview with the HR. Then after about 1 week, you will have the tech interview which includes ml questions, stat questions and behaviors questions.
