Why does mobile app testing feel like a never-ending battle? 📱

If you're building mobile apps, you know the struggle: your app works perfectly on your X device... but crashes on Y, looks weird on small screens, and has more quirks on older OS versions.

This is mobile fragmentation – an ever-expanding universe of devices, OSes, screen size…

When you hire engineers, it’s often tricky to figure out if you should hire a junior, a senior, or what skills to hire for.

To figure this out, I have found that a useful question to ask yourself is:

What can you mentor people on, vs what should they bring from home?

Most of the times, you should only hire for the latter.
