Goldman Sachs has multiple interview rounds.

• The first round is a HackerRank test, where you need to solve two problems in 90 minutes.
• The second round is a CoderPad round, also with two problems, but you have 60 minutes to solve them and must cover corner test cases. In this round, a senior interviewer will call you directly and expect you to discuss your approach before solving the problems.

Following these rounds, there will be four Zoom interviews. In each of these four rounds, a panel will give you one problem and expect you to discuss your approach before solving it. Multiple technical questions will be asked during these rounds, based on your profile and resume.

After the technical rounds, there will be a managerial round, followed by an HR round.
