After a lot of struggle I finally got selected at a company in Germany. During initial rounds I deferred the salary expectation part partly because I don't know much about German ecosystem as well as I don't wanted to miss the chance. Also, company is bearing the VISA expenses of me and my wife too.
I finally got the offer with HR telling me that there are some areas of improvement specially in the communication part. The HR told me about compensation during the call and asked me if I am ok, that time I said yes but after talking with few of my friends I found that the salary I am being offered is just average salary and whose large chunk will be gone in tax part.
I am married so I was expecting something generous and I was told that they will keep that in mind. Now, I have the offer letter with the compensation on it and I have to sign and send it as soon as possible. I am worried if I can negotiate the salary or not and to what extent and I don't want to loose the offer too.
Also, should I ask them if they can provide me some bonus upfront so that I can manage my expenses for first month including rent etc?
I am really bad at negotiation and I don't want to regret later on.
PS: I can disclose the amount hope it doesn't violates any company policy.
