Our client is a dynamic and electrical start-up with own product.

They offer a platform that aims to make health care accessible anywhere, anytime and for anyone.

Their culture is:
  • Everyone manages their agenda, know when to say no to work, and when to warn team of late work. There’s no good reason to not deliver on the expected (and revised) time.
  • Open communication: everyone can speak to everyone. Projects which imply changes in due dates require discussion with managers, but other than that handle your agenda.
  • Say what you think, discuss and challenge, but ultimately trust the decision of the ownerof the project. That’s how we get openness and everyone’s voices heard, but also get accountability.
  • If you are unhappy with a person, with your position, with your career plan, with your salary, or with lunch: tell your manager. If you don’t trust your manager, make yourself heard through someone you do trust. No one will fire you, you won’t get into trouble. Enjoy the ride, there’s no point at going through the pains of moon travel if you don’t enjoy the views.
  • Make yourself accountable for results. Errors, or success will never be entirely your fault or grace, they will always be for lack of process, multiple errors/successes of peers. The only way to improve is recognizing what we can improve, and celebrating what we are doing right.
  • Make yourself available. Your success will depend on other’s work, and they will be going out of their way to help you. Do the same. The only things worth doing are the ones you do for others.
