I applied online. The process took 3 weeks. I interviewed at EXL Service (New York, NY) in Jun 2019
Interview
The process consisted of 3 rounds.
1. HR Screening
2. Technical Interview - The interviewer was good. The questions were framed in a decent manner. SQl based questions. Some machine learning concepts
3. Technical Interview - The interviewer was very arrogant. Asked unrelated questions which involved puzzles. He was not ready to accept any other answer other than the one which he had with him. Waste of time interviewing.
4-5 rounds, prepare your resume , sql, case study , probability, python , puzzles .
SQL and general case study in first round. 30 min round .
2nd round python pandas question etc.
3rd round puzzle , why you want to join us and more sql .

easy but not formal, over all, its not intense, one with hiring manager, one with client, for the client side, he just asked about easy questions about excel , and chat about weather
I applied through a recruiter. The process took 1 day. I interviewed at EXL Service in Feb 2024
Interview
A SQL question followed by A/B testing question (interviewer was pretty less knowledgeable on this). Finally questions on PowerPoint that can be easily googled. Bad job description and an even ill-fitted interviewer.
