AppDynamics Senior Software Engineer interview questions

I applied to job on their website and recruiter contacted me. Round 1: 1 hour interview with hiring manager. Interviewer asked some behavioral + some technical questions. They checked if my experience aligns with the work that their team does. Round 2 & 3: Each interview lasted for 1 hour. Leetcode easy/medium questions followed by lots of java fundamentals questions. One of the leetcode question was related to multithreading. Round 4: Approx. 40 min behavioral round with the director. Interviewer asked basic questions related to my project and some behavioral questions.

Very disappointing. Hacker rank then coderpad then coderpad and so on till the time you fail it. Its all waste of time they have rejection policy so not worth opting for it and wasting our time
