In summary, the process was too long and they expected a lot of my time during normal working hours. This is really hard to do when you are currently employed elsewhere.

They also asked for a test that, on average, should take 10-20 hours of work, which seems excessive for someone who may have many processes running in parallel.

In general, there seemed to be little care for the prospective employee, and I hope this attitude doesn't translate to current employees.

Why do you want to work here?

Where do you see yourself in 5 years?
