IBM Software Developer interview questions

I had only 2 interview stages. it took 2 weeks. However, I even didn't have a call with a recruiter. We communicated only once by email. 1. The first stage was - to make 2 tasks on the platform Hacker rank. One task was about to delete specific combinations of symbols from the string, the second was about that we have a wheel with alphabet letters (A-Z), we can move in clock wise direction and against. And the goal is to find the minimum time. When the recruiter got the results of the coding assessment and realised that I was suitable for them, we arranged a technical interview. 2. Technical interview was nice. There were questions about Java Core, Microservices, Docker, Linux, REST and testing. I was waiting for an answer for 3 weeks.
