Happiest I've been in my career
Pros
In two days' time, I will have completed my first year at Checkout.com and this is what I have to say... I wish never to have a reason to leave Checkout.com. I absolutely love it here. It' the people who make it so enjoyable. I joined in July last year and it has been amazing to watch it grow from around 300 people to >700 to date. It's been exciting, challenging, and rewarding. Strong working relationships made with people in other teams and departments you'd not normally be able to do in most companies. I've never been a part of such a sociable and culturally diverse company before and one that recognizes you for the value you add, no matter how big or small. Supportive management and growth opportunities in your career. I feel like I've finally landed on my feet here and my career is on track. I don't believe anyone who has a bad thing to say about Checkout.com. Checkout.com is going places, so don't miss the boat if you are thinking about applying!
Cons
Nothing that I can think of. But my advice is; If you can't hack 'fast-paced' it might not be for you.
