Goldman Sachs Java Fullstack Developer interview questions

Initially there was a hackerrank test. I got a mail from hr that I have cleared the test and next will be coderpad interview. They asked for the slot which I am available for. In the coder pad round there were two questions. The interviewer was friendly and was giving hints. I wasn't able to crack the most optimal solution for second question. Questions were medium level data structures ques. I got the mail from hr the same day that I haven't been shortlisted. Overall a positive experience in terms of quick communication maintained in the process
