Interview:

1st round: Online assessment with 2 questions to be completed in 1.5 hours.

2nd Round: A full day of assessments, with each round being an elimination round.

There are 10 business units, and each business unit has infinite accounts. Each account has a TIN which is of 9 digits. One account out of all these does not have a TIN of 9 digits. Find that one account.
