It was a technical client interview.

This candidate showed up 10 minutes late. His connection was terrible, but he claimed it was definitely my connection (I was in and out of calls all day, including the very same call with a recruiter, and my connection was perfectly fine). I didn't want to confront him, so I just spoke very slowly and clearly so he could understand me.

The candidate was really impolite. He asked me to share my screen because he wanted me to put everything in writing, but he could not see it due to his connection issues. Then he insisted he needed me to do things quickly.

He then sent me a Google Doc and asked me to describe step-by-step how to do certificate pinning in Android. It is a really simple task; you basically download a certificate and add it to the APK, then you add a public key in your code, and that's pretty much it. However, he wanted more steps (which both I and the Android SDK documentation do not know how to do).

Next, he asked me to start up Android Studio and do some very simple code: two fragments and the communication between them. While I was doing it, he clearly switched tabs from the interview and seemed to have gone on with his own life. From time to time, he would switch back and change the instructions. Then he just assumed, from the top of his head, that I was having issues with the code and asked me what challenge I was facing. I was just building whatever he told me to build last, with no issues, but he kept insisting on it.

Five minutes from the end, he interrupted my coding assignment and asked if I had questions for him. I had three questions:

• What does your company do?
• What software development process do you use?
• What's the tech stack?

He answered each of them with a single word and then said, "Thanks for your time," and left.

1. Write in a notepad how to do certificate pinning in Android. I need you to do it very quickly.

2. Start up a new project in Android Studio and create an activity with two fragments in it (each one taking up half of the screen). He wanted the app to receive a web address from the user, and then load it in a WebView that was in the second fragment.
