Other Data Engineer Interview Reviews for Boston Consulting Group
I had 3 rounds, one with RRHH, one technical interview (with live coding) and the last one was just live coding. The last round was a complete disaster, the interviewer doesn't want to be there, was just looking the phone the whole time, when speaking he doesn't look to the camera so the voice was horrible and hard to hear him.

Interview
Got a call from Naukri.
Step 1: OA on CodeSignal. UI was really bad, solved 2/4 questions and got selected.
Step 2: Online interview. Basic SQL and Python questions. Asked to convert SQL to PySpark. Easy.
Step 3: In-person interview. Asked mostly about work experience, tech stacks used, etc. Asked Python questions based on string. Asked to optimize a PySpark code snippet.
