The process took 2 days. I interviewed at EXL Service in Jul 2024
Interview
Had a video interview. Asked me to describe a project at work; it was on forecasting so he asked me to explain arima; as I am explaining ARIMA I mention stationarity so he asks to define it. I am defining it (and say its specifically for weakly stationary) and he gets completely confused when I am explaining the autocovariance condition(and apparently he has stats MS??). He then asks me about what covariance is,and the linear regression conditions; I list three of them and he asks about each one. He also asks about the main function in Python. he then ends it 20 minutes early.
Didn't pass the round, probably because the interviewer cannot understand the autocovariance condition.
Interview questions [1]
Question 1
Define ARIMA, stationarity. define covariance. what are the linear regression assumptions, what is the main function in python
I applied online. The process took 2 weeks. I interviewed at EXL Service
Interview
The second round consists of a technical interview focusing on Python, machine learning concepts, and AI-related questions to assess problem-solving ability. It is followed by a fit round that evaluates cultural alignment, communication skills, teamwork, and how past professional experiences align with the role and company expectations.
I applied through a recruiter. I interviewed at EXL Service (Gurgaon, Haryana)
Interview
Interview was good and detailed. Asked about Generative Artificial intelligence and Machine Learning. Some questions were asked about Natural language processing with python coding.
It was 3 round interview and 2nd was technical followed by a HR negotiation round.
I applied online. I interviewed at EXL Service in Feb 2026
Interview
It was a virtual interview, but updates on my application stopped. The interviewer seemed uninterested very much, leaving me uncertain about progress and disappointed with the lack of communication and engagement.
