Got an email asking me for a commitment date to complete a technical assessment. I set a date, but there was some problem and when I tried to access to the technical test, I couldn´t (got a message about expired test). After a number of emails with no response, I got another email to set a new commitment date. This time I could do it.
It is a pretty easy task, but the day after finishing it I got a generic rejection email. I honestly don´t know why I did wrong, but that probably means that I should not pass the test.
