Multi threading, data structures, hashing, capacity of datastructures, architecture of current project, project management/scrum related questions, performance tuning questions. I sat through the whole day and completed all the process, which is very exhausting to say the least, finally HR said I am through and discussed about package, date of joining benefits etc. Then they said I can leave for the day and they will inform me about joining formalities etc. For the next 4 weeks I kept calling them and my recruiter without any response, initially they said due to Christmas and new year panel is on leave, and response is positive and they will release the offer soon. However to my complete disapointment after one whole month they said they have rejected my candidature without giving any reason. Strongly recommend not going here, utter waste of time and efforts. If they dont have interest/budget to hire why bother calling candidates and waste their time. Suggest anyone going here think twice, this could happen to you. Better stay away from this.
