Couchbase Software Developer interview questions

Amazing interview process. First round was couple of easy dsa questions like two sum and find if the array contains 50% of the same element. This was followed by concepts like parallel sort, threads and concurrency. Second round had one design question wherein in I was asked to implement malloc, free and compact function keeing fragmentation concept in mind. Third round was also a design question in which a large file was given and I had to efficiently read and find out prime numbers. Fourth round had one coding question given limited time of 10 mins which I couldn't crack. All in all one enligtining day.

- multithreading - dsa - cuda - c++ , python, java threads - golang questions - generics in c++ - need to be crystal clear on OS, DBMS(NoSQL) concepts - emphasis on c++/multithreading projects on resume, no importance given to either ML or python projects done (good thing since its a systems based company and applicants dont have ML stuff in resume anyway)
