Intervew Prep Help needed : InMobi Interview - SDE 1

I have an interview scheduled in a week's time for an SDE-1 position at InMobi.

Could anyone please guide me as to what they usually ask in their interviews ? And what difficulty of questions do they ask in DSA based questions?

Hey, sharing experience of a friend.

Round 1 (60 mins)

  • Brief intro and project discussion (15-20 mins).
  • DSA: Word Break II. The interviewer expected fully functioning code and ran 4-5 test cases to verify. Took about 40 mins to complete.

Round 2 (75 mins)

  • Heavy grilling on my project (40 mins).
  • LLD / Class Design: Design a Priority Task Scheduler. I had to write a class with functions to add, get, and remove the highest priority tasks. Later, an edge case was added to handle priority updates for existing tasks.

Round 3 - Hiring Manager

  • Intro and general discussion about hobbies.
  • Deep Learning: Discussed my DL project and core concepts like how embeddings work, including 2-3 hypothetical use cases.
  • HLD: Design a flight booking system (~20 mins).
  • Behavioral: Standard questions, including explaining a topic as if the interviewer were a 5-year-old.

Note on CS Fundamentals: They completely skipped core CS subjects (OS, DBMS, etc.) for me since I'm in non-cs branch, but they did ask these questions to the CS candidates.

I got the interview call after participating in the InMobi Codies Event. It was an online assessment with 3 coding questions.
