I applied online, and the process took five days.

There was an email to arrange a call from an HR person or recruiter. She did not show the first time, and I emailed her to set a different time. She was late for the call, and I wish she had just not bothered. It was a very rude interviewer who told me I did not have experience scaling apps, but the technical buzzwords she was using were not even correct. It was a frustrating experience to be told I do not know anything about technology from someone who is not a developer. I tried to explain to her how scaling in blockchain works, but she kept saying I did not know what I was talking about. I talked to a friend who interviewed, and they had the same experience last year with the same person. I've been to a meetup at their office, and everyone seemed nice, so the rude experience with the interview was surprising.

Describe how you built and scaled an app.
