WHAT WILL YOUR RECRUITMENT PROCESS BE LIKE?
A fair approach to all people who want to join T Hub means that:
The recruitment process is transparent;
Our recruitment decision is based solely on an assessment of your skills (your race, skin color, sexual orientation, gender identity, origin, disability, political view, appearance, or religion will not have any influence on he outcome of the process):
Regardless of the outcome of the process, you will get detailed feedback.
Let's meet to better understand each other's expectations.
Our screening meeting will last about 20-30 minutes. We will ask you about our areas of interest and will be happy to field any questions you may have.
Hiring Manager will receive a recommendation for your application.
There's nothing for you to do at this stage - we'll take care of everything. During this time we process all the information we've gathered during the screening process and dig deeper into your CV.
Technical meetings with the Hiring Manager and/or team members.
We will invite you to one or two project meetings to confirm that we have a 'perfect match'. The meetings may last between 30 minutes and 90 minutes, during which time we will talk to you about mutual expectations and the vision for our collaboration. You will also most likely meet your future supervisor and your teammate during this time.
Time to decide!
At this stage, we will have decided that you are the person we want to develop our projects with. We will then come back to you with an offer of collaboration, hoping for your "yes". If for some reason, we are unable to offer you a position in our team, you will certainly receive feedback from us explaining our decision.
