There were 4 rounds. 2 technical rounds,1 manager and 1 HR round. In technical rounds they asked questions related to javascript, Angular services,Directives, pipes etc.
Some CSS and HTML related questions were also asked in 2nd technical round. I got call directly from GE healthcare talent acquisition team. Interview was on saturday,it started around 10 a.m and i completed HR round around 4:30. I just wasted my whole day and they didn't gave a call to me till one week. Then after arond 1 and half week they gave me news that some approval issue is there so give manager round for same role in another team and we will take it forward. I mailed them and called multiple times for scheduling the new manager round.They don't even responds to mails and calls. It's completely waste of time to go for interview with wabtec.
