Mobile Developer Intern Interview Questions

2,734 mobile developer intern interview questions shared by candidates

The interviewer started explaining what was expected of me and a brief explanation of how the platform works. The code problem was a typical easy-medium problem you find on leetcode or hacker rank. I first explained two different approaches I could do to solve it, and the interviewer told me to go or one of them. After testing a couple of edge cases, they asked me to think if there were any other optimizations I could do and also, prepared the solution as if I was going to submit it on a Pull Request.

4th skype (design round): - How will you design an app (client) & server to implement a word guess game. For e.g. app will ask user to guess the word (it will show blank spaces first equal to size of the word) one character one time. He will have 'n' chances to guess correct word. Based on the result, he will win or loose money (prize). Assume you have well defined payment & user registration system. Assume external systems required for this game already present. Just concentrate on designing the above core requirement
