Technical Coding System Design
The interview process was super long, like 4 months, from mid-Jan to May. It had 3 online rounds, 1 online test, and 2 in-person rounds. They mostly asked about Data Structures and Algorithms, a bit about Databases (writing queries), and some Puzzles. For DS & Algo, topics included trees, Linked Lists, DP, and Backtracking. The main goal was to see if I could think logically, come up with efficient solutions, and write code.

So there were 5 rounds in total, 4 of them were technical. It started with a phone call, then an online test on HackerRank. After that, the remaining technical interviews were at their office. The questions were medium difficulty and included puzzles, algorithms, data structures, and JavaScript/Angular topics. I passed everything and got good feedback, but they ended up not offering me the job because they needed someone who could start immediately. This wasn't mentioned before, and it felt unprofessional to not give an offer after I cleared all the stages.
