Backbase Backend Engineer interview questions

Overall process took around 1 month, 1 round: general discussion with HR, like why you are looking for change, introduction ,sal expectations. 2 round: home assessment on codility challenge. 4 tasks will be there... 1 algo question and 1 MCQ (spring), JPA , small rest service. 3. technical round: 1 or 2 devs will be taking interview and questions will be on core java,springboot,microservices,K8 & docker, AWS(a less knowledge also fine), spring security(OAuth),maven 4.manager round: more on the cultural and soft skills , but I had got rejected in this round. According to me everything was going smooth... but seems like hiring manager already liked someone for the position and therefore from starting of interview.. didn't even smiled a single time , he was not friendly and no intro was given and when i asked to tell something about him, i got a reply "Why you wanna know about me" strange but somehow i managed to get his introduction. Overall it was very good exp other than last manager round. rest all people were very friendly specially HR of backbase is really very cooperative and friendly, sharing my interview process. So that everyone would aware , this may happen to anyone .
