      Average interview

      Application

      I interviewed at Hella (Gurgaon, Haryana)

      Interview

      The hiring process was disorganized and unprofessional, with a Python requirement raised mid-interview despite the take-home assignment being entirely in Python. Interview questions were too basic for a Lead-level role, with no system design depth or genuine technical engagement. The interviewer was sarcastic and dismissive, and made incorrect remarks about the submitted pipeline work. The interview ran 50 minutes over the scheduled time, and all questions about the project were met with vague, non-committal answers. The role has been open since January, and the entire process felt like a formality with no real intent to hire externally.

      Interview questions [1]

      Question 1

      Basic AWS , sql and difference between python and panda based on the offline assessment.
