The technical interview had a lot of questions regarding Java/Kotlin, Concurrency, JMM/Memory leaks/Garbage collection details, and RxJava. The team fit interview was just me going through all of my previous jobs and trying to explain what value I brought there. Also, they wanted me to elaborate on some of the recent challenging technical problems I resolved at work.
