I gave interview and it is very pathetic experience. I am having experience as full stack developer but interviewer ask only about linked list. I told him that I never used Linked list. I use map as collection. But he didn't ask any single questions about map or other data structures. Or related to java, spring , hibernate. I still design linked list but again asking questions on over of linked list. I suppose he did not any other data structure. Rude behaviour of his is that he asked me how I will review junior on basis of data structures complexity. Boss, we need to check first impact and compatibility of structural ,we are going to use. Other as per JDK change, we should need to be more flexible. Just checking on complexity does not come as parameters for review. And even data structures is not mentioned under their shared JD. Just wasting our valuable time and money .
