Process was fairly simple. I received an email a day after I sent my CV asking me to participate in a phone interview on the same day, I then used this day to prepare for the phone interview and the questions involved were very much CV based, asking questions like "how you found the transition from A levels to university" as well as general questions about Cognolink and what I thought they did. The interviewer then allowed me to ask questions myself, this is very important as it demonstrates to them that you have a genuine interest in the company so use this to create a really good impression. I was then called back three days later for a face-to-face interview.
The second stage involved two back-to-back interviews with two different senior managers at the company, both of which were very friendly and easy to get on with and made the interview process much more relaxed and less nerving. My first interview was CV based and the interviewer really wanted to find out my motivations, strengths, weaknesses etc as well as asking a lot of questions about my CV such as the internships I've been involved with as well as my degree. The second interview was largely competency based asking questions like "tell me when you worked in a team" etc as well as a case study. The case study was definitely the hardest part and it's the reason I didn't get the job. It's also arguably the most important part because such scenarios will happen on a day-to-day basis at the firm. I would definitely advise practising this as much as possible. Also your commercial awareness will really be tested so the days prior to your interview make sure you keep up to date with all the current business news, read FT etc.
