Had two sets of interviews (one with a senior ops analyst and one with an investment analyst), I had felt that it went decently well where I had good conversations with the interviewers and talked about my work experience. The interviews progressed quickly as it happened about 1-2 weeks after each other. Afterwards, I had received a take home assignment where I had the weekend to do the assignment and submit via email on the Monday. Completed the assignment and submitted on time, and was immediately ghosted after submission. Tried following up and they did not respond.
