Lithium Technologies IOS Developer interview questions

1) Aptitude Test 20 questions need to answer in 40mins which includes Pattern Recognition, Problem statements, 2) 2 Rounds of Technical Interview 3)VP Round 4) HR Round. No matter how much experience you got, if you aren't clearing the Aptitude test, you are gone. I have seen a person with 12 years experience attending the interview was rejected for not clearing the Aptitude Test.
