Round 1 is a short phone interview. It's pretty standard and I think almost everyone passes round 1 as long as there are no major red flags.
Round 2 is a behavioural Skype interview. Since most people are ready to answer questions about items on their resume, they twist it a little bit and ask about your high school experience instead of university experience. Be quick and natural and you'll be fine.
Round 3 is another Skype interview, more on the technical side. I got a case on pricing Timmies products but it was probably the easiest case I've ever seen (and I'm not even experienced in cases). There is some basic math involved, but it's VERY basic. The final product recommendation was super easy, it was the option that was the cheapest and had the highest revenue. TLDR it's easy.
Round 4 is super day at their Oakville HQ. Morning starts with a review of RBI, tour, etc. Round 1 of the day is literally a business game where you work in a group of 4, each group is in charge of a different region (AP vs. North America, etc) and each region has different criteria for growth, price elasticity, etc. There are 4-5 round, and each round you can change price, ad budget or a couple of other factors and they have a simulator that gives you the results of your changes. If you do terrible on the game, it doesn't mean you're out but it does count against you a bit. Just make sure you can justify your answers and even if you screw up, make sure you explain why you think that happened.
After that it's lunch and then after lunch they cut 1/3-1/2 of the applicants. Final round is a rapid fire panel with Tim's C-level execs (CEO, CMO, CFO). Key is to keep your calm, and explain your answers. It was actually not as scary as people make it and I had fun doing it. There is the classic "who would you hire/fire on the panel question".
All in all process was pretty fun, recruiters were nice and I learned a lot.
