It was an on-campus opportunity.

First, there was an online assessment (1 hour) on HackerRank:

• 4 aptitude-based MCQs (all easy, 14 minutes)
• 1 SQL query (easy, 10 minutes)
• 2 DSA problems (1 easy and 1 medium, 36 minutes)

Followed by Interview Round 1 (30 minutes).

(As I heard from my peers, it was resume-based. Some students were only asked about AI/ML as they had mentioned it extensively in their resumes.) In my interview, the interviewer was really very friendly and asked me 1 DSA problem (medium to hard), DBMS (schema design + queries), and resume-related questions.

Followed by Interview Round 2 (45 minutes - 1 hour).

The interviewer was more professional than friendly. The interview started with resume-related questions and continued with system design (HLD particularly). This round was very technical, and the interviewer asked about implementations in detail.

OA:

• DSA: One was greedy (easy), one was line sweep/prefix sum (medium).
• SQL: Subquery + join with filtering and ordering (easy).
• MCQs: Aptitude and DSA related (easy to medium).

Interview R1:

• DSA: Heaps (medium-hard).
• SQL: Queries based on schema design (basic-easy).

Interview R2:

• Resume related: In detail.
• HLD: Particularly web-related questions, very technical.
