I was contacted by a recruiter with a job advert. The recruiter asked about my current CV and directed me to the company website to upload it with a reference ID.

There were three rounds:

• Screening
• Take-home project
• A few on-site rounds

The decision was announced via the recruiter. They also required a criminal background check in the UK and in my home country, which took a few weeks. Additionally, a university credentials check and two references were required.

The process was quite complex, and it has since been simplified. It was impressive.

They don't ask silly gotcha coding questions. They heavily test basic CS fundamentals, but they do so intelligently.

Mobile platform questions include:

• Simple coding questions in Java, Objective-C, and C++.
• Questions about platform APIs (basics to check if you truly code in it).
• Multithreading concepts.

Take-home assignment: An optimization problem (I believe they no longer do this) with elements of OOD.

On-site coding round: LeetCode-style puzzles, basic CS concepts, data structures, threading, memory management, and code review.

On-site design round: Designing a complete mobile app, frontend and backend (architecture, no visuals). They discuss various constraints and changing requirements as you go to check if your design is adaptable.

On-site company culture fit round with the manager.

HR round with compensation expectations.

On-site team culture fit round with the direct team lead.
