I applied online. I interviewed at Mentor IMC Group
Interview
Two 1-hour long interviews, very informal chats and then a formal presentation on the industry. First interview was with one manager, second (presentation) was in front of 5-10 people in the office.
Applied through recruiter, got an email offer and then a Skype interview a week later. Was asked behavioural questions, and about my resume, professional experience, education:
"Tell me about yourself"
" Why do you want to work here?"
"Why do you think this internship suits you?"
