Graduate Profile: Jonny

Degree Course studied: Computer Science (BSc)

University attended: University of Sheffield


What attracted you to apply to PortSwigger?

“The emphasis on my personal development was huge for me. I knew I still had a lot to learn and wanted to do it in an environment where there is a lot of focus on me, as opposed to just being another graduate on a massive scheme.”


How did you find the recruitment process?

“Simple and friendly. I saw the advert on my Uni careers page and emailed the company. They rang me for a discussion and a few questions about Java, it was all very relaxed and I was given the chance to ask my own questions. This was the case again in the face to face interview when meeting everyone.”


What are your early impressions about the graduate programme you are on?

“Very good! I have been given a lot of resources to aid my development and everyone is willing to take time out of what they are doing to explain new things to me. The working environment is fun and friendly, trips out for lunch and to the pub happen often and also the working hours are flexible, so I can shape my week exactly how I want.”
