I applied online. The process took 4 weeks. I interviewed at Colas (Birmingham, England) in Mar 2026
Interview
The role was for a buyer to support many projects, but the Interview felt quite intense and was more directed towards project management questions. The expectations for the role was set quite high and I was advised several times the role is office and site based, no working from home. I didn't get a positive vibe from the senior buyer and tbh I kind of gave up trying and thought I wouldn't want to work along side someone like them.
I had applied online, then had a phone call to come in for an interview. Interview was very relaxed and talked through my cv, my course, experience and interests. Talked about the role and if it all suited me and then got a phone call offering job a few days later.

Entretien RH
Mise en attente 1 mois sans réponse et se plein des relances.
Experience deplorable malgré la qualité de certains interlocuteurs chez Colas.
Certains RH n'ont aucun respect pour les candidats, pas de lecture de CV, infentilisation, conseils déplacés.
