A very standardized process involving:

• An initial call with someone unfamiliar with the position, who asks numerous questions and assigns a "brain teaser" exercise within 30 minutes.
• A subsequent call to learn about Microsoft.
• Five consecutive interviews (in-person or online during COVID) where basic but detailed undergraduate-level questions are asked, even for Master's or PhD candidates.

The manager does not appear to listen (confirmed by two other interviewees).

• Bayes' theorem
• Binary search
• How to apply GANs in medical images (while the interviewer does not listen to you)
• Multiply a bunch of numbers
• What is the heap?
• What's the limit of the Python stack?
• Name the most famous algorithm in Deep Learning
• How many lines of code have you written at most for a project? (-.-)
• Do you know unit testing?
• What's the last paper you read?
