I applied online. The process took 1 day.

The application process is fairly straightforward: fill out a standard online Greenhouse form and append a CV to it. Trivially, one is required to fill a series of mandatory questions too to this form. If you're seeking to demonstrate your understanding of your field, you will naturally take a portion of your time to elaborate with depth and nuance. For example, when asked about a technical challenge, it seems infantile to simply say, "complex UI logic due to ambitious UX", etc. You will go into detail, which takes a portion of time to do so well. See interview questions below for a sample of the rest.

Anyhow, my experience is that the HR team rejected the application without any feedback. As mentioned to the HR team, it'd be useful to receive a modicum of feedback if you are to understand that iOS engineers don't simply disappear into the ether. We're here to stay in the industry, so if you truly wish to "hope you'll consider applying for other roles with us in the future", then perhaps query some token feedback for engineers as being useful even at this stage, particularly for a senior with 7+ years here. Hence the review. I cannot reconcile to expend my time or recommend others to do so when this is considered as acceptable feedback management. Best of luck to the company and recruitment process!
