If you have successfully passed all these steps, congratulations! The HR department will get back to you with a salary offer.
Except in extraordinary cases, you will then have from a few days to a week to consider the offer.
Use that time to weigh up the pros and cons of the offer. Do not accept the offer impulsively and then go back on your decision, as this might damage your future credibility.
And rest assured, turning down a job because it is not what you are looking for does not mean the Arkema Group's doors will be closed to you.
But if the answer seems obvious, then do not delay! Come and join us!
