Technical Behavioral

It wasn't too bad, the person interviewing me was really modest. I'm hoping to get to the second round, even though they tried to negotiate the salary, which is a bit stingy for an MNC. Still waiting for the results.

Technical Coding Other

The OA had 40 MCQs split into ML and Maths, plus Aptitude. Then there were 2 elimination rounds. Round 1 focused on projects, feature engineering, Python, and ML. Round 2 covered projects, ML, and Deep Learning. Usually, one candidate is picked after all interviews. The company is SanDisk, not Western Digital; they've separated again.
