Group One Trading interview questions

The interview rans ~4 rounds if I remembered correctly. First ones were mostly behavioral and running through resume. The last one was a few intern candidates (~5) doing round-table, with technical questions, statistical/probability-related

Had a 20-min on-campus interview with HR lady, only behavioral questions are covered. Very smooth process and I thought I did well, however didn't make it to the second round which might be more technical.
