Sabre Java Developer interview questions

Applied online got an invitation for hirevue interview and hackerrank assesment , after completing that got an email 3 months later saying that i am still under consideration. Never heard back again. The company did not have the minimum decency to reply (despite me sending many emails). Worst interview experience ever. What a waste of applicant's time and effort.

I had total 4 technical rounds.1st round was online test. Test was based on mcq and coding questions. After clearing the test 3 more technical round 1:1 and 1:2 basis. It took 1 full day to complete all the rounds. Questions were basically from java basic and conceptual. They asked to write few codes using java. Some brain storming and interesting questions were asked. Everyone was friendly in behavior.
