Oracle Principal Software Engineer interview questions

Are you ready for the next rung in the ladder?

15 minutes interviewer argued why cloud deployment is necessary. Now who will tell him that it is because of to minimize cost of infrastructure, reduce the time to develop and with minimal maintenance resources, scaling, providing HA.....Only God knows what he wants to listen. Questions asked more like overloading, hashmap.....Interviewer is not interested in listening the answers. He is just trying to portray himself like he is Java creator. For 15 mins he was asking me priorityqueue. Till last I am not able to get it he is trying to ask to code priorityqueue with DS logic or implement it using exsting java.util.priorityqueue as example. "He is also very poor in communication not able to explain the questions properly.' Second interviewer seems like 3-4 years exp and he just stuck in Spring postconstruct implementation...how you will implement your own.Gurrrr..how one can remember all the spring core inside implementation. In nutshell both the guys seems very immature in taking interviews of any senior candidate. They should ask some design questions , some architecturial questions. Seems like they are not doing any new stuff like cloud computing/big data technologies Don't waste your time in this boring company.
