The interview began with brief questions about my past software development experience and knowledge of networking. I was interviewed by the Technical Lead right off the bat, which is uncommon.

It was a video call using Webex, which, for some infuriating reason, didn't allow me to connect over Wi-Fi. I had to call in over the phone, which the Lead was okay with.

It sounded like he was 10 feet away from the microphone, which made it super difficult to hear properly. I got annoyed when I had to ask him to repeat questions.

Technical questions were straightforward:

• Debug a program
• Code another program in a language of your choosing
• Calculate the Big O of the program

I was also tested on basic concepts of RTOS.

Calculate the Big O of the given program.
