There were two phone calls, a take-home test, 1:1 in-person interviews with the art director and senior designers. It took a long time to get the final result.

Heard back through email from HR after an online application. I was connected to the hiring manager and we had a 30 minute phone call. I was then given an unpaid design test which took about 3 hours or so in total. I followed up a few days later after sending my work in to get feedback and was told they were still reviewing apps including my work. Almost 2 weeks later and I haven't heard back after sending one final follow up. If you ask prospective employees to do free design tests, it's polite to at least give a simple email saying thank you but we're going another direction. Ignoring us after we've spent several hours on work is rude.
