The interview was a mix of technical and managerial. There were a total of 4 rounds, starting with an online assessment on HackerRank, followed by 2 technical rounds and 1 managerial round. The Online Assessment had two medium DSA questions and 6 git MCQs, it was time-bound and an eliminator. Round 1 focused on basics, DSA, deep JavaScript and Typescript, React, and web optimisation. It also included JS output questions on async programming. Round 2 involved discussing and then implementing a solution to a problem statement using React, with follow-up questions on design patterns. This round was about 1.5 hours. Round 3 was with a senior manager, focusing on past experience, project impact, and security questions like CSRF and XSS. The final HR Round was a 30-minute discussion about the motivation for joining and expectations.

It started with an online assessment (OA) that had one DSA question (easy-medium difficulty) and some MCQs on CS fundamentals. Then, there were 1st, 2nd, and 3rd technical rounds. The 1st technical round involved 2 easy-medium DSA questions, SQL, discussion on projects, and CS fundamentals. The 2nd technical round focused on SQL, design patterns, and CS fundamentals. The 3rd technical round covered CS fundamentals, one medium DSA question, and projects. Unfortunately, I didn't make it past the 3rd round and was rejected before reaching the 4th HR round.

Coding Technical Behavioral
I went through an HR interview, then a solo coding challenge, followed by two technical interviews. The technical interviewers seemed unprepared. One wanted me to design a DB ERD but didn't have a way for me to draw it, so he switched to asking me to write a simple Controller in my IDE. While that was acceptable, I think the process could have been better planned and rehearsed. I repeatedly asked for feedback from the technical interviews and the HR rep. The HR rep initially said he'd get back to me but then completely ghosted me. After four interviews, I expect some kind of update, whether good or bad, and feedback. This was very unprofessional.
