GoJek iOS Interview Experience and Question

Round 1 - Profile Selection

Go-Jek HR contacted me via LinkedIn. After expressing my interest in the position HR set up a quick phone call. In this call, HR told me about the Go-Jek products and it's existence. Also, HR asked me about my experience and some basic details about the current company. Here if you have any questions about Go-Jek, or around the role that you are applying for, you can ask them in this round.

Round 2 - Assignment

After the phone call. HR sent me an email with a problem statement. I've to submit the solution in 5 days. Here the guideline which I've to follow -

Your selection chances are higher if

• You use the latest version of Swift
• You adhere to Apple's Human Interface Guidelines and coding conventions
• Your app performs well in terms of CPU, memory and energy usage
• Your code is loosely coupled, testable and uses an architecture similar to VIPER, MVVM, MVP, etc.
• You tastefully customise the UI and add animations etc.
• Your app does not have too many dependencies on third party frameworks

Your application may reject if

• Your project fails to compile or compiles with warnings with the current version of Xcode
• Your app does not layout correctly for all iOS devices that can run the current release of iOS
• Your app has UI/logical flaws that make it difficult to use
• You do not have UI and unit tests in your application with decent code coverage
• Your UI/unit tests fail

Other Notes

• We expect you to use git and commit frequently
• You should submit your solution to us as a zip archive
• The zip archive should also include your git commit history
• Please use system fonts everywhere. It’s not important to match the font size with the design, but you can infer the sizes from the designs

Problem Statement

You can find the complete problem statement with a solution here.

Round 3 - Assignment Review

Once I submit the solution, Go-Jek evaluates it by an automated system that validates basic hygiene factors like if code contains git logs, readme or not, etc..., and if that clears, a senior GO-JEK engineer check quality and design. The problem statement has the above rules. So, pay attention to them.

Go-Jek HR reply me after 3 days by saying, I'm happy to inform you that you are a "pursue" from the assignment stage and we'll soon be scheduling further rounds of interviews for you. After this, I choose the day that I want to go to the Interview. You can choose a day based on your convenience.
