Am I able to contact the respective company about questions regarding their job ad?
Jobmensa is a platform for companies to advertise their job offerings for you to apply for them.
We simply forward your application to the respective company and are therefore unable to offer further information regarding the job ad other than what is written in the advertisement itself.
For further questions regarding a job ad you are able to contact the respective company directly once they contact you, e. g. when inviting you for an interview.
Either way you should always apply for a job if it appears interesting, even if you still have questions after reading the ad. In your cover letter you are also able to include information upfront, e. g. regarding your available work days.
