Summary

I interviewed for the Associate Production Engineer role at DeltaX through an on-campus drive, successfully navigating four rounds including MCQs, coding, AI-based telephonic, and a personal interview, eventually being one of the two selected students.

How it went

🧪 Round 1 (MCQ Round)

  • The round was 45 minutes long and consisted of 50 MCQ questions from topics such as DBMS, Operating Systems, OOPS, and Pseudocode.
  • Out of 1385 students from my college, only 101 were shortlisted for the next round.

🧪 Round 2 (Coding Round)

  • This round was 2 hours long, but each of the five questions had an individual time limit.
  • We were not allowed to switch between questions once a question was started.
  • The questions were mainly based on arrays, strings, and hash maps.
  • One of the questions was Combination Sum II.

🧪 Round 3 (Telephonic Interview)

  • This was an AI-based interview, where the interviewer already had access to my resume.
  • The questions were primarily based on my projects and the skills mentioned in my resume.

🧪 Round 4 (Personal Interview)

  • This interview lasted for approximately 1 hour.
  • It started with a brief self-introduction, followed by an in-depth discussion of my projects.
  • I was then asked one DSA question based on Dynamic Programming, which was a variation of the 0/1 Knapsack problem.
  • Additionally, I was asked to design a database schema for Spotify, followed by several discussion questions on the design choices.

✅ Final Result

  • Only 2 students were selected from my college, and I was one of them.
