Possibility of hiv exposure? Exposure?

  I went to do Health check up in a lab facility.  The phlebotomist of that lab after drawing blood from my vein did not used cotton to stop the bleeding he instead used his finger with which he had gloves on after sometime very later he used alcoholic cotton rub but there were 3 more people who drew their blood before me and  He didn't change his gloves the whole time he drew blood of all of us and I am assuming he used the same fingers and same technique to stop the blood of all the three people before me after drawing their blood  , there was a gap of 1-2 mins in every person turn and I was at the last . So do I have to worry for an HIV exposure ? Because there are mixed answers from in the internet some are saying that HIV becomes inactive in few seconds outside host and there are some answers that it stays for 5-6 hours and even a week in dried blood .
