TCW- Associate Credit Analyst 3rd Round Interview

I applied to the Associate Credit Analyst position in Fixed Income at TCW and made it through the 1st round and the case study/ credit pitch and was recently invited to meet the team in person for a 3rd round. The schedule is a full day of meeting team members in individual and group settings. I am meeting a range of junior and senior team members. I haven't had an interview process like this before, as my current job I have held since I graduated and had a significantly different process, so I'm not really sure what to expect and how to prepare. I would appreciate if anyone has any insight on the interview process, either if they have got through it at TCW, or something similar.
