4 rounds of interview. All technical. Every round you need to prove that you know Java. Final round was F2F having already cleared 3 rounds of hard technical interview. Was asked to sit in a cabin and given white paper code assignment. 20 mins interview asked only 2 questions. Total waste of 1 month time having cleared 3 rounds of technical interview they still ask you to prove that you know java for 10 years old experience person.
