I applied through an employee referral. I interviewed at eBay (Brisbane, CA) in Jul 2017
Interview
I got this onsite interview at eBay after a share screen coding interview. The onsite interview took 6 hours. I was asked questions about coding, machine learning algorithms, and my data science experience, as well as some open end questions.
Interview questions [1]
Question 1
Build a model to identify customers interested in receiving ad emails.
Machine Learning questions like boosting, bagging and stacking and so on.
Had two rounds of interviews, mainly asked questions about python, SQL and machine learning. And it was not really well because the process was different from the description in the email.
I’m not sure how I got this interview, as it was heavily focused on machine learning. It started with a hiring manager interview, where I was asked many in-depth questions, including how to choose a model, how to tune parameters, and how to evaluate model performance. I don’t have a strong background in machine learning, so I wasn’t able to answer many of the questions and didn’t move forward after the interview.
I applied through a staffing agency. I interviewed at eBay (Bengaluru) in Oct 2025
Interview
I interviewed for the Data Scientist position at eBay Bengaluru and had a final interview consisting of 3 rounds. After completing all rounds, there has been no communication or feedback from the recruitment team despite multiple follow-ups.
It’s very disappointing to see such poor candidate experience from a reputed company like eBay. If they take the time to conduct multiple rounds, the least they can do is respect candidates’ effort and provide closure.
This kind of ghosting after the final round reflects poorly on their hiring process and company culture. I would not recommend anyone to waste their time participating in such unstructured and unprofessional hiring drives.
