I applied online. I interviewed at IBM in Jan 2025
Interview
first was an OA with 1 python (medium) 1 SQL (easy) question. Then had a technical on ML/DS trivia questions and concepts and then 1 easy python + 1 easy SQL question live coding. Final round was a behavioral with emphasis on the consulting / client facing side of the data scientist job. Ended up declining cause the job requires a ton of travel and I didn't want to do that unfortunately.

It was a good experience overall. The assessment was conducted online through HackerRank and was well structured, focusing on problem-solving, logical thinking, and fundamental technical concepts in a clear and manageable way.
Interview questions [1]
Question 1
They asked questions focused on SQL and LeetCode-style problem solving, mainly testing logical thinking, data handling, and basic algorithmic concepts.
I applied online. The process took 2 weeks. I interviewed at IBM in Sep 2025
Interview
Applied and next day received a hacker rank.
SQL easy,
BUT LEETCODE MEDIUM
Required depth first search of an acyclic directed graph, and minimize the required changes so that a condition could be met.
SQL took me like 8 min but the LEETCODE one I couldn't get right. Code complied and all but didn't pass the test cases and timed out for some.
Hadn't seen or practiced a tree traversal question in years much less one that combined trees with minimization problems
Interview questions [1]
Question 1
Similar to LEETCODE 1135 but harder.
Had two dozen test cases this question
