I applied through college or university. The process took 4 weeks.

R1: DSA Coding Round Three graph-based problems.

R2: Aptitude Test 30 questions based on mathematics and physics.

R3: Hackathon Part-A A 3-hour coding challenge titled "Tree of Space."

R4: Hackathon Part-B This was an intense full-day interview (11 AM - 7 PM) with multiple sections: Core CS concepts interview (2 hours) Two DSA problems (Medium + Hard) Thread-safe implementation of my Part-A solution Project discussion

R5: System Design Interview This was about Computer Architecture, Security, OS, and System Design,

A puzzle on a code which should return which elements to pick to maximize the score for player 1 (there are two players 1 and 2).

Assume an array: [2, 4, 6, 10, 8, 16, 12, 1] If P1 and P2 can pick in turns alternately, how to maximise A's scores
