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.
