They contacted me through an external recruiter and asked me to go to their office for a face-to-face interview. The first interview was not technical; it was rather about my career path and similar topics.

After some weeks, I had a technical interview with one of their Heads of Engineering. He asked me rather theoretical questions about the Android OS and its architecture. I also had to complete a test on the Java programming language and C.

Few days later, I was asked to complete two online tests:

• An IQ evaluation
• A psychological assessment

After some more weeks, I was called to be told that I had been selected but wouldn't join until several months later.

In the end, they never called again. When I got in touch with the HR manager, he started giving me some poor excuses about delays and "potential follow-up" the following year.

Of course, after this frustrating experience, I gave up on them.
