GroundTruth SRE/DevOps Engineer interview questions

Got contacted by the manager to have a 30 minute chat. He then forwarded my application to the HR person. The HR guy scheduled a further 30 minute chat, which he cancelled 10 minutes before the appointment asking to reschedule for Monday. I supplied a list of time intervals, one of which was 8.30-9. When I checked my email around 8 on Monday morning, I found out that I was scheduled for 9 am few hours ago (there is 3 hours difference between our time zones, so the HR made a booking around 5.30 local time). I replied that 9-9.30 was not on my list of available times. Then I get an email at around 8.25 if I am available for 8.30. I was not around to read this, and I just had a facepalm moment around 9 am. The following day, I get an email with apologies for the confusion and letting me know that the position was filled and the meeting would not have made a difference. Dodged the bullet on this one.
