It was enjoyable. There were 5 rounds leading up to the final interview / assessment centre, which were all online tests / video interview type thing. The penultimate stage (job simulation involving video interview and having to write emails) was tough, and I didn't think I passed, but I got through, and the assessment centre was better. I prepared quite thoroughly with a lot of examples in STAR format, I had about 10 different examples / scenarios and projects and that really helped I think. The assessment centre day involved a group case study, which was quite challenging but the best advice I can give here is just, be yourself, be nice and courteous, and be as helpful as possible. Don't try to outshine anyone else, just try your best to support the whole group, and do as much as you can individually to help. If you do get an opportunity to put yourself forward, definitely take it (for example, if they assessors ask 'who wants to present the findings - and the group hesitates - it's a good chance to put yourself forward, but ask if anyone else wants to present with you). Here they are mostly looking at collaboration ability. I had to give a pre-prepared presentation, which I prepped for a lot, but I took note cards which helped my confidence and this was fine. The partner interview was really enjoyable, try to just treat it as a conversation, ask as many questions as you can, and try to be human and maybe make the interviewer laugh once or twice. Acknowledge their humanity and that they have a long busy day of interviewing, and try to make it a pleasant experience for them, rather than worrying too much about delivering a perfect performance. By this stage, you have already passed all the competencies, so it's just about being nice, personable and demonstrating that you can fit in with their values (read up on these beforehand).
