Ultimately, it was a positive experience. Everyone was very polite and straightforward about what they're looking for. You'll have a phone interview followed by two on-site interviews, a skills assessment and then a personality assessment. The skills assessment is pretty straightforward if you're any kind of an accountant though I would recommend brushing up on the more obscure aspects of accounting from your 101 classes so that you're ready to go. The personality test isn't really something you can "prepare" for so just don't let it get in your head and answer honestly. My only recommendation here is to practice some of those "the next number in this series 1, 5, 16... is?" questions. There's a "trick" to tackling them you just need to be ready for it.
Given the length of the personality assessment, I suspect this is a key metric in making a hiring decision and if so my only gentle recommendation would be to perform this test up front rather than at the end of the process. It's important to remember -though understandably easy to forget- that the interviewee has also put in considerable time to prepare and money to get out and meet the team. In the end, you can save yourself and the candidate time and money by getting this done on the front end.
That aside, I was pleased with the process and felt it was fair/friendly.
