GSK Statistician interview questions

Phone interview followed by on site interview. The interview day is about six hours long, but not intimidating and includes lunch and a site tour. They allow time to get to know the site and employees.

The worst interview experience ever. I don't know if they recruit people through recruiting company or what, the people who gave a call today is super unprofessional. They said my name wrong twice and tell me to prepare for background question, really personal offensive question. I felt really uncomfortable, i interviewed with a lot of company before, none of them ask me 'From June 2017 to August 2017, tell me what did you do?'
