Difficulty of even getting an interview despite booking. Needs a more seamless process. First attempt was that I was not even called despite correcting my skype details and informing them immediately as instructed by the Admin. Second attempt was Admin's skype was blocked and was not even in information given until the allotted time passed. Third, was told that I did not have a scheduled interview despite booking beforehand and sending in the necessary screenshots from website and confirmation email. Then was told to reschedule again beyond the 30 minute grace period. The only booking left was 4:30 the same day but could not book it once Test Call Admin informed me I should take it because slot was taken.
