I am currently finishing my internship for the last year of my engineering Master's degree.
Many recruiters/companies have already contacted me and I started the recruiting process with a few of them. Of course, the usual "how much do you want" question happened.
Because this is totally new to me, I had not really thought of the salary I should have been asking for. As a result, I asked for roughly 4k€/y less than what I could have (compared to friends, family, colleagues, school statistics and fellow students).
Is there a way for me to correct this ? I feel it is not a good idea saying "oh well I changed my mind and raised my expectations".
So far, I said that other companies offered me more (which is true) but did not give any specific numerical value.
As a side note, this is happening in France (in case it's useful info)
EDIT : Although I chose Lilienthal's answer, thank you for the advices which are all relevant. The offers I received caught me completely off guard but now, I know I can correct things. Thanks for your help.
