Senior iOS Engineer Interview Experience - San Francisco, California

August 1, 2019
Negative ExperienceNo Offer

Process

The process began with an initial phone interview with the hiring manager, followed by a coding assignment. They indicated the coding assignment would not take more than 2-3 hours.

After submission, I received a general rejection email. I asked the recruiter for feedback, but none was provided.

I had followed all best design practices, including the use of Coordinator, MVVM, and Dependency Injection, and had even written valid test cases. Despite this, I still received a rejection email.

Companies need to understand that candidates are often working full-time jobs, and dedicating 5-6 hours to a coding test represents a significant effort. Rejecting a candidate without giving them an opportunity to explain their work on the assignment feels somewhat harsh.

My advice to candidates: If possible, avoid coding assignments. They are time-consuming and often not worth the effort.
