There were 4 technical interviews and lunch with a dev manager who asked soft questions. 2 interviewers asked coding questions. Both were about games involving matrices of numbers. Not hard, just need to figure out how to traverse the matrices and operate with the numbers on it. One them also asked some questions about SQL, basically about joins, group by, having and sort by. 1 interviewer focused entirely system design. There were lot of questions on queue system, caching, load balancers, micro services. 1 interviewer focused in front end. Some questions about HTML, Javascript, ajax, etc. Basically, all knowledge questions. He said it was mostly just to make an assessment but it was ok If I didn't know the answers. Finally, the lunch interview had lot of questions of the type: tell me about some project you worked that you are proud of.
