The application process was quite fast probably because they need several hardware design engineer during that period of time. I submitted my online application on 10/01/2017. Then I received their reply after 1 week that ask me providing some personal additional details and working eligibility in UK. After another 1 week, they sent me an online test link which is about the fundamental questions of digital circuit design. then after 2 weeks, they emailed me asking my availabilities of atending their interview in Bristol. The interview was quite relexing. Just two interviewers, one of which is the leader of Bristol branch and the other is a serior hardware verification engineer.
It was my fault that didn't make a good preparation for the technical questions becasue I thought it was going to be a general first-round interview testing your personalities and teamworking ability. Actually the interview was quite a technical interview. They asked me sevelral questions about the D gate circuit. Such as set-up time, holding time of the input and the propagation time of the output. the answers can be found on google.
It was an good experience at the beginning of my job hunting. Wish my share can help you in your difficult time.
