Interview questions [1]
Question 1
I didn't like their interview process. There was no HR who will contact you to regarding interview date and time. The interviewer at the screening level starting conversing on whatsapp which is not at all professional. Next day morning it was a telephonic round on basics of Big Data, Spark,Python. later on, another level of whatsapp video call interview happened, no HR contacted regarding time and day of the interview. The interviewer himself called on whatsapp via video call. This was not a professional way of calling an interviewee.
Next day another senior person(maybe a manager) called me to meet them at Gurgaon location. On asking about interview call letter/mail by HR he seemed disinterested and told will drop a message of company location in Gurgaon. I didn't went for this F2F interview as it seemed highly unprofessional.
I applied through a recruiter. I interviewed at EXL Service (Dallas, TX) in May 2026
Interview
2 rounds worked successfully. I received feedback for recruiter saying "Client didn't shortlist' you profile, I will re-submit your profile for future requirements from client". That's the end of the process.

I applied online. I interviewed at EXL Service (Bengaluru)
Interview
Both the interviews went great after the second round, I was told that I am not selected but could not give the reason for it. Even after following multiple times.
The first round was a technical interview focused on Python, SQL, and data engineering concepts such as ETL pipelines and data processing. The second round was a managerial-technical discussion where I was asked about real-world project experience, problem-solving approaches, and system design scenarios. The final round was an HR discussion covering behavioral questions, salary expectations, and overall fit for the role.
