There were 3 rounds of technical interview happened. But they hold further process for next 2 month, Then rejected me. This happened repeatedly 2 times. Warning here please don't waste your time for this interview process.

I applied online and I had an initial call with a recruiter followed by a call with the hiring manager. The call with the hiring manager was mostly based on experience and I was not asked any specific technical question. Unfortunately I was rejected with no feedback, my best guess is they are looking for the perfect match in terms of technologies used in the previous role. For the role I applied they were looking for Java, Scala, Spark, Kafka experience.
