it has 4 round. phone screen--> coding test about leetcode hard one-->technical interview about machine learning questions and system design-->hiring manager
after one month, I got no feedback. this part is quite annoyed.
I applied through a recruiter. I interviewed at Baker Hughes (Houston, TX) in Jul 2020
Interview
2 interviews, ones technical and one HR, about 1h long each. The HR one was less behavioral than usual HR interviews, and felt like the company was not really interested in hiring anyone but rather using interviews to solve their own technical problems by stealing ideas from candidates.
Interview questions [1]
Question 1
Technical interview: A few basic problems were sent a week before the interview, covering data science/processing topics such as data cleanup, extrapolation, training a decision algorithm, analyzing sentences.
HR interview: "We would like to use machine learning to do this, but we face such and such problem. How would you handle that issue." is representative of most questions during that interview...
