Candidatei-me por meio de uma agência de recrutamento. Fui entrevistado pela General Motors (GM) (Detroit, MI) em abr. de 2017
Entrevista
I recently flunked the iOS engineer interviewing process over at GM / OnStar so I figured it might be useful to recap my experience so the next candidate (i.e. you) will have a better idea of what to expect for when you walk in the door.
The way the interview worked was that there were two lead developers in a single room with me along with the hiring manager (i.e. a panel interview of sorts). One of the devs gave me a laptop with Xcode on it and asked me to come up with a simple no-interface iOS app that describes a typical game of bowling. In other words, given two raw API names (e.g. “roll” and “score”), how would one implement this using TDD?
They were immediately not impressed with my efforts because the definition of their demo project was so vague, I had to ask (apparently too many) questions to try to get some clarification and focus out of the developers interviewing me. Prior to the programming test, they also asked me to describe how I would remote start a car via the Apple Watch and they definitely did not like my answer on the white board there either.
In terms of the environment that I saw, the cramped floor of the RenCen seemed mostly full of offshore agency contractors fresh off the boat, but they do also source a lot of local contractors via DetroitLabs. The programming process that was described to me sounded like peer programming, where two developers are working on any one task at any one time. One positive thing was that they said they do have mildly flexible hours (where some folks come in early and others arrive as late as 10 a.m.), so anything to get around the rush hour gridlock that accurately describes all the expressways leading into downtown would be a good thing.
If I had a chance to do this interview again, I would probably bone up on doing a demo app entirely via tests. I’d also probably ask less questions and let the interviews do the driving.
Hopefully my experience flunking the iOS Developer interview process at GM/OnStar will help you to prepare for yours.

Good luck to you!

Pergunta 1
How would you implement a minimal game of bowling in Xcode using TDD?
The only API’s you need to implement are “roll” (a ball) and “score” (to get the current score).

They asked me to do one assessment which i did in less then given time even after my busy office day at current work, and i got feedback that i have asked to do that task someone else, thats so rude and negative feedback i have ever got from anyone. Even during interview one guy already soud so rude while asking me anything.

Entrevista
I had applied for contract position. The interview was arranged for 90 min. There was a panel of 3 members consisting of a manger and 2 technical Interviewer. It started with technical question and answer and later the interview asked me to build the iOS App. But no prior instruction was given that I should be prepared with the app building environment instead I was told by the recruiter that online IDE will be shared and I will be coding on it. I had joined the meeting through the laptop given by my employer company which unfortunately was windows and I told interviewer that I have connected through windows and asked them to give me sometime to connect back through my personal mac. And the day was just not right, I was unable to login to Skype for Business through my mac so I asked them if I can join through personal Skype Id and the Manager said they will continue with questions and schedule another round for building the app. I asked for feedback and they said I was pretty good in this round but they need to test my iOS app building skills in next round and wrapped up interview. When I asked my employer if they got another slot, my employer told that GM doesn't want to proceed which seemed unfair. I would appreciate if General Motors can tell candidates in advance about such instructions so they don't loose the opportunity. I felt the interview process was unprofessional and interviewers were in rush to wrap up the interview.
