Bottomline Software Developer Fresher interview questions

I get a test link after referral. I cleared this test for next round. Got a call from HR a week later that I have been cleared the test and interview tommorrow. Interview was on webex. First they ask me to write a query in sql. I have done using group by,inner join and order by. Then they ask me 3 puzzle. So basically it was more like puzzle interview. I could not answer any of them.
