Postmates Software Engineer: IOS interview questions

The interview process was a very positive experience. Really smooth and professional. Got in touch with a very nice recruiter who scheduled a technical phone interview for me. The phone interview was done on coderpad. Then proceeding to the on-site very quickly. At the on-site, first was a Engineering Director who asked about some interesting programming problems about algorithms then shared his stories about how he chose to joined Postmates and why. There was lunch with a few engineers on other teams, everyone was super friendly during lunch. Had a chance to just sit at one of the tables to eat, random people came and go so I had a chance to interact with some of the other people in the company from various teams. The vibe was really great and very positive. People joked around and seem to be very happy. Everyone seemed to be having a fun time there and had good relationships with each other. After lunch, there was an iOS engineer who presented a project with a few bugs and was ask to fix it. The engineer was very helpful in discussing the decisions I was making and open to provide his feedback and thoughts. Third, was tested on creating a application that does a specific thing. It's nothing crazy difficult but rather a very fun challenge to test your practical iOS skills and interact with the interviewer and bounce off ideas and come to a best solution. Then there was a cultural fit interview the VP of engineering, who was very informative and transparent about his visions for the company and how he plans to lead the team. Last, a very nice conversation with the recruiter that asked how I felt I did and touched base on some other related information regarding my job search. I felt like the interviewers were all very experienced interviewers. Knew when to give helpful hints and when to sit back and let me figure things out. The best thing about it was I felt like I was tested on many different areas of my skill set. It wasn't algorithm heavy or anything super crazy but rather a fair and broad assessment of my overall skills in different areas. I felt like I was given a fair opportunity to demonstrate what I can do in very practical areas and how I think logically when solving problems. I was sad that I didn't end up taking the offer but this was honestly the best interview experience I ever had in any of my job searches. Responses were quick, things were very organized and set up efficiently. The package was very competitive and fair. I can't think of one bad thing to say about my experience at Postmates. If you are preparing for this interview, my advice would just be open and talk to the interviewers as you are trying to solve the problem. They are nice and are willing to point you in the right direction. They were also willing to answer any questions I had during and even after the interviews. Brush up on some practical iOS skills that you could encounter in a real iOS application. Know your basics and you should be good, good luck!

Entire interview process with Postmates lasted almost 2 full weeks. There were 1 initial phone conversation, 1 Skype + online coding interview, then one on-site interview that had 3 coding challenges and a few non-technical sessions that didn't feel like interviews at all. Overall, it was pretty challenging, yet very positive experience. Everyone was very welcoming, made sure I felt comfortable. They understood that the interview process is always stressful to candidates, so they did their best to lessen the stress.
