On 15–17 February 2021 there will be a three-day fair where over 150 companies participate on the online platform. In addition to this online platform, for a select number of companies a real-life exhibition will also take place in the foyer and canteen of the TU Delft Aula Congrescentrum.The TU Delft Aula Congress Centre will be completely converted to a fair where selected companies will present themselves with a stand, in compliance with RIVM (Netherlands National Institute for Public Health and the Environment) regulations.

Here, they will tell you exactly what working for the company means, what career prospects there are and what kind of students they are looking for.
