Frequently asked questions

What does resourcing mean exactly?

You will be employed in a dynamic work environment by Competa. As a colleague, you will work as an external expert for one of our customers. What kind of project this is depends on your expertise, ambitions and place of residence. You will come back to our office between projects and are always welcome to join us for drinks or at company events. Even if you are on a project, you can ask your colleagues for help or stay in touch through Slack. In this way we ensure that you have one permanent employer, are stimulated in your development and at the same time can look into the kitchen of several organisations.

How long does a project take?

A resourcing process via Competa takes an average of 9 a 15 months. The duration may vary. Ersan is our project length record holder with 8 years at KPN. Counterpart Jeroen, on the other hand, was on a project to help a client fix an Angular problem in only 24 hours.

What if I don’t like the project?

We always try to find projects that suit you. If it turns out you don't like the project you're working on, tell us. We will help fix the problem or look for something else for you. It is important to us that all our colleagues have a good time.

Do you go to a client alone?

It depends. Sometimes you go alone, sometimes you go with multiple colleagues. It’s not uncommon to go on an external project together with colleagues as a Scrum team.

What if there is no suitable project for you?

It may happen that you're not on a project every day. Then you will work at our office on internal projects and your personal sprint. To keep your skills up-to-date and you will be ready for the next project we find for you.

What do you do about development opportunities?

Personal development is very important for us. We have a budget ready and help you find the courses to improve the skills you like.
