I applied online. The process took 3 days. I interviewed at Amadeus (Waltham, MA) in Feb 2019
Interview
Interview process was average difficulty , got the offer and accepted.
Just 1 week before joining they rescinded the offer. i actually had 2 more open jobs offers but i rejected both for this firm and now i am back again in market after 2 months.
They have very poor planning for extending offers.
