I applied online. The process took 2 weeks. I interviewed at Tessian in May 2019
Interview
In first round i got rejected (hackerrank). Question was pretty easy. but unfortunately Electricity of my area was gone around 1 hour and 20 minutes (during test time). And at the last 30 minutes i implemented code which was partially correct. I wish i could have another chance so that i can express my skills again but i accepted situation and moved forward.
I would say interview process is clear and straightforward.
