There is an application which you must fill, then a assessment centre which is usually physical but mine was virtual. The assessment centre consists of a 30 minute presentation and 30 minute interview
They give you an auto OA first but they don’t resume screen you before hand so even if you pass the OA it doesn’t guarantee you the next step in interview.
Didn't hear back after automated online assessment was sent to my email, not an interview but it was the online assessment. I was sent many from IBM but no hear backs even though I solved them.
