I applied online. The process took 1 week. I interviewed at Visa Inc. (Bengaluru) in Jun 2025
Interview
The first round consisted of an online assessment with three coding questions. Two easy and one medium level. I was able to successfully solve around 2.5 questions.
The second round was a one-on-one technical interview that focused mainly on SQL concepts such as window functions and joins. It included around two easy and one medium SQL question, along with one easy-medium level Python question.
The overall difficulty was moderate, with SQL being the main area of focus. Unfortunately, I couldn’t progress to the next round.

I applied through an employee referral. I interviewed at Visa Inc. (Bengaluru) in Mar 2026
Interview
First technical round: Coding—Python, PySpark, SQL one question each
Second technical round was really weird. The interviewer didn’t switch on her camera. She asked no questions about my resume. She asked me Python, PySpark, SQL questions. (Really easy like window functions and lazy evaluation, wide vs narrow transformation.) No followup questions. I answered all of it and then she ended the call twenty minutes early.
Seemed disinterested and eager to get it done with.

Interview
Once you are pre-screened, you get a codesignal test. Once you solve at least 2 out of 4, you are invited to a 1st round interview where they ask you basic sql and python questions.
2nd Round - my interviewer was very condescending and got offended by my definition of a data engineer. Their communication style included remarks that felt condescending, such as implying a question was "sixth-grade level," despite it being a specific Python trick. This made the interaction quite unpleasant and difficult.

How would you read 1 TB file using spark's inferschema option.
Good interview process. Starts with a online assessment with questions starting from easy to hard (according to leetcode). Then interviews. 1st round - technical. 2nd round - techinical. 3rd round - technical and managerial
