Career Stories

    "I came across Prove while contemplating an internship through my school's email. The place sounded cool, so I decided to apply and got in. When I started, the vibes were great—friendly atmosphere, nice people, neat facilities, and smooth operations. Everything was fantastic. It still is, but the initial morning jitters have eased. I've been with Prove for a little over two years now, primarily working on intensive testing projects. I've been involved in usability, accessibility, and device testing. The best part of the job is the variety; it's enjoyable to switch between locations, projects, and products. The best thing about Prove is the company culture. Everyone is considered to be on the same level, and you can do your work independently. The atmosphere is more laid-back than what you might expect from an IT company."

    "I ended up with Prove by chance when I happened to discuss with Jaakko Sakaranaho as my thesis was nearing completion, and I was contemplating future career plans. I asked if Prove had a need for an employee, and we scheduled a meeting for the following week. During that session, we planned a product for security testing. My time at Prove has been interesting, as I've had the opportunity to work on a new testing product and enhance my testing skills. It has been challenging at times to make progress, but it has been a rewarding and intriguing experience. I particularly appreciate the freedom to create working methods and tasks, allowing personal growth and development."
