I applied through a recruiter. The process took 2 weeks.

It starts with a: Round 1: MCQ round (Maths, CN, Physics, Aptitude) Round 2: Coding Test (3 Medium - Hard Questions) Round 3: Hackathon Coding Round (1 Question on M-ary Tree) Round 4: DSA interview Round (20-30 mins). Question - We need to find all different connected components and check if they're complete graph in itself.

Round 5: Hackathon Part B (Worst Round) (Interview took 8-10 hrs and after 2 days they say you're not good fit for the company) Question: We need to use multi-threading and locking on the Hackathon question. Easy right? I also thought this but You can't use any inbuilt function or any inbuilt mutex or any inbuilt time variable. You can only use arithematic operations which are atomic. Still it's not hard to get answer. But, interviewer just know one solution. And wants us to get to that solution. I gave him 4-5 different solutions with best TC n SC as possible but all he say is that ok this may work but can you use something from node variables. I used.

Then he said can you use something else. And he let it run until 9pm. Interview started at 11 am. Total waste of time. Because when i asked in the end if this round is supposed to be this long they said we just wants to test if u can fit into company culture. Can you cooporate with others and can you sit 9 hrs on the desktop for the job. I mean... ok nvm. Even after so many rounds there are supposed to be 2 more technical interviews and Hiring Manager round.

MultiThreading on M-Ary tree and lock the states.
