Goldman Sachs Software Development Engineer interview questions

There were 3 rounds(2 Technical of 1 hr and 1 HR of half an hour) In technical rounds they focused on coding skills + Data structures + projects In HR they focused on how important I consider Goldman Sachs offer.

The interview mode is good. first round: Hacker Rank first array based problem (easy question string compression input: waaarrziiiii output: 1w3a2r1Z5i) second question : dynamic programming (a=1,b=2 given number how many such strings are formed) second round : coderpack test where one guy will peep you screen what ever the program assigned and asked you to code the same. 2 programs will be assigned to you. (I think atleast one you should pass and next you need to attempt and give solution) Program was Pascal triangle. Third round: technical ,mgr ,hr and so on. This HR is so clever she asked me leave for the day without evaluating my skills. In round two I was about the complete the program system got restarted due to maintenance activity. Interviewer selected me by asking few questions what is my approach documented my inputs and he said you are selected and wait in the lobby for the next round. HR came to me leave for the day and we will get back to me next Monday. Asked me to leave for no reason. I wasted my time twice. Three years back I got selected for next technical discussion due to unavailability of panel members I was rejected. Now system crash I was rejected. you should respect the candidate who appeared for interviewer. Time and money involved. (transport fare and half a day precious weekend time ) If you evaluate the candidate completely then call them up for interview else please don't call.
