I found this interview unprofessional and an unpleasant experience. I was very surprised to receiving an invitation for a 2 hours test. The email had not description no introduction after took me some time to identify the source of the email by searching the name of the person on LinkedIn, check my applications, looking at the email address I manage to identify. We are all humans and value our free time and there are a lot of great companies out there, but if you as the HR cannot take 5 minutes to write me an email to introduce yourself or give me a call in advance to be asked to do a test, why wold I give you 2 hours of my time to work with you. I will avoid this company.
