Pluspunten
Gillware is a really neat place to work with some awesome perks. They're flexible as it pertains to taking time off, work/life balance was great (at least in my role), and free lunches every Friday are pretty great too. There are also some absolutely brilliant people working there, figure out who they are and try to learn from them.
The technology they work with is also fascinating and it was exciting to learn how such complex machinery works. Most people don't really understand how data storage works.
Minpunten
Data recovery is an intensely customer-focused industry. People are often very passionate about getting their data back and you need to a.) be willing to go the extra mile sometimes for the customer and most importantly, b.) don't take it personally when a customer or other employee gets upset with you. The passion that sometimes causes people to get upset in this business is the same passion that makes recovering someone's treasured family pictures feel that much more rewarding. Heck, on the digital forensics side they've even helped put murderers away. Very cool.
Also as others have stated, you need to be driven. Everyone is already busy trying to do their own jobs so if you want to succeed, come with a good work ethic and a propensity for learning. Worked for me, but it's not for everyone.
