First stage: a short phone call with HR for initial screening. Second stage: an online coding test on Codility from home. Third stage: an in-person interview at the company's offices, including SQL questions, C++ programming, and an oral question.

SQL: Two questions involving JOIN, GROUP BY, and aggregate queries on data tables. C++ (coding): Finding an element in an array that first increases and then decreases, using a linear pass over the array. Oral question: Row with maximum number of 1s – a sorted binary matrix, starting from the top-right corner, eliminating rows and columns in linear time.
