Interview process involved several stages. In my case there were two telephonic and one programming problem and a face to face interview. People who took interviews were quite arrogant and were not technically sound. They were not willing to listen to the logical answers rather sticking to their own narrow vision of technology. I am not sure which department they work in. The attitude of few interviwers was like they dont give a damn about your answers, they just wanted to listen to what they know. I hope they will improve and become a bit professional rather being childish during interviews. It felt like they did not research properly around they questions they were asking. Also there response during several stages was very slow. I am not sure who handles the HR process in Cambridge but they kept me in limbo for days before coming back with an answer. Being a tech company its expected that if you do not find candidate suitable or up to your expectations then please do not keep them in limbo. If you dont like a candidate then just let them know politely rather keeping them in wait for months and then coming back with you copy pasted email. I hope their technical people improve their behavioral skills and HR people start doing their job efficiently.
