I was recruited on LinkedIn.

There was one phone screen, followed by a loop of five interviews, four of which were technical.

The interviews focused heavily on native development in a mobile language.

I specialize in a different aspect of low-level mobile development, but none of the interviews delved into that, so I would say I only did "okay" on the technical interviews.

I was told I could choose whatever language to interview in because they were "language agnostic," so I chose C++.

It didn't matter; after the phone screen, the rest of my interviews were in Kotlin, which I have less experience in.

Overall, I would say the experience would have been positive, but they spent a lot of time delving into Kotlin when I indicated upfront my strongest language was C++.

The hardest question was to fix failing unit tests in a Kotlin project. This was for a function that parsed an authentication header.
