First round was an informal chat with the hiring manager. The hiring manager was very pleasant and considerate. It felt like a fantastic opportunity and an amazing team.

Then the process moved on to the technical interviews.

The first technical interview, and please note I've been interviewing for over twenty years... Was write a full asynchronous demo, using threads and with nonconcurrent dictionary to show how it's not thread safe.

Then fix it.

It was 30 mins. It was a car crash. Maybe I should have been able to do it?!

I spent two hours after that setting up my old legacy example then using DI and the decorator pattern (with semaphoreSlim) to show how I would wrap the old third-party (closed) dependency.

I sent them the git repo link.

I got some tosh back and decided to remove myself from the process.

I think what annoys me more than anything is the total disdain for the candidate. There was no prep, no partial code, no guidance.

I don't care who you are writing code in web browser window with no auto completion or debugger is horrible.

When will these firms learn?
