unprofessional. very chilled out atmosphere. not a stressful interview. just know the basics and typical interview question. nothing more to know of at that point. It was okay and not uncomfortable at all.
I applied through an employee referral. The process took 2 weeks. I interviewed at Interserve (Birmingham, England)
Interview
Phone interview asking basic question like why do you want this job, are you able to commute, have you used Excel before, do you have AAT qualification etc
