Question 1
How would you integrate a machine learning model into an existing enterprise system?
The first round was a tech assessment containing two questions one for testing arrays and strings and the other for testing database knowledge. But the questions were of medium level and not easy
Applied for the AI Engineer internship at IBM. Did not receive an interview, but I did complete the coding assessment. It consisted of two LeetCode-style questions, one easy and one medium. Both were straightforward standard algorithm problems, nothing AI or ML specific. No behavioral or technical interview stage was reached. Overall the process felt impersonal with no feedback provided on why I wasn't moved forward.
