About before experience, projects and technical skills.
The hiring manager acted more like an interrogator than a professional interviewer. He tried to find contradictions in my resume instead of asking deep questions about how I did my prior projects. For example, he wanted to put me in a corner that GPT 3.5 was not issued when I claimed it in my resume, while he was wrong about the issue date of GPT 3.5. See, how cheap were his questions!
We discussed a number of things, e.g., some machine learning questions.
- Tell me about your experience in ML and your resume. - How to deal with seasonality in a time series. - What is a decision tree. - What is bias vs variance and how to treat them. - What is price elasticity. - How to convince a senior executive that data science is important (duh! seriously, I got asked this question by the person who was looking at another screen and was not even listening!)
I do not recall the questions, generic data science questions.
