Absolutely unprofessional. I was asked to solve 2 simple tasks at pre-screening process. You had to log in and solve tasks in a specified limit (1.5 hours). I apologized I was on vacation to which I got as a response a template-sounding reminder that I should do it ASAP. I did in the last day possible and because of different timezones I logged in a couple of minutes after the deadline. So I did log into the system solved the tasks and waited. After 2 weeks I received the following email: I’d like to extend my sincerest gratitude for you interest and time given toward consideration of our upcoming Hiring Event in Prague, Czech Republic. Unfortunately, your skills assessment was submitted past the deadline and was not considered for the event. Which made me throw up in my mouth. So those guys allowed me to solve the tasks, waste my time and then they discarded the whole thing without even looking? This company clearly doesn't have appreciation for the employee's time. I won't disclose the questions though because you know, I was too specific with the email I received and the Amazon guys might end up suing me.
