HCLTech Mobile App Testing interview questions

I have got call from HCl Technologies Hr people that job opening for Mobile App testing . During interview schedule itself I have asked whether it is complete manual testing / Mobile Appium automation testing but Hr replied in call that it's for manual opening but when I attended interview ETA techno park (Navallur) past week as waited around more than 3 hrs. Hr people informed me that we are specially needed for Mobile Appium tool that is being irrating one waited for longer hour & no proper response from Hr people. Not sure what requirement that Hr people are gathering out before they are scheduling the interview call.
