I've seen the advert on StackOverflow and applied via careers page. I got contacted by HR a couple of days later. Interview process has following steps: 1. HR 30 mins. talk about the company, your background and expectations. A couple of behavioral questions. 2. Technical Challenge They send you a coding challenge and expect you to complete within 7 days. You should be careful about everything while building application like design, architecture, unit tests, ui tests and etc. Then you send the application for their review. They care about quality of the code especially clear code and structure. Please be aware of SOLID principles. 3. Technical Interview If your application is considered to be good on their side, they will send you a request for technical interview. In this step, you should be talking about every design decision, application structure, tradeoffs and libraries you used. They will ask you basic iOS questions. 4. Meet with Engineering Manager If you pass the technical step, you will be meeting with engineering manager. You will be asked a bunch of questions about your current working environment and workflow. You will come across a couple of behavioral and case based questions. 5.Meet the Team You will meet the team that you will be potentially working with on video call. It's a casual chat between team members, questions about you and you can ask questions them too. 6. Offer If your feedbacks are good, they will immediately call you and give you an offer. Later on, they will send the details about offer via email.
