Good Energy interview questions

I was referred by my friend who also worked there before & Good energy was actively looking to hire candidates due to many employees leaving in bunch. Pushed my CV to the HR & got a call immediately . Scheduled interview in 5 days time for one to one with the Project Manager. As the company premises is next to the council office , there is no facility of parking , therefore has to use station car park , then walked my way in for 5 mins. Arrived around 9:00am & was received by HR , then was escorted along to the interview which lasted about 40-45 mins. Once , i was out , got a confirmation call before EOD and was asked for immediate joining.
