Well, that raises the debate whether innovation is spawned by necessity and problems, or whether it is spawned by forward looking ideas for which a market still needs to be created.
It is certainly both and working for a company which enables them and your personal growth is IMO more important than how the first day went. Choose the company wisely and you will be fine.
If it takes too long to get your user ID and password and correct access, then you know that other processes don't work well either.
Your first few days at work are your days. Employers dont remember. Even 6 months are not remembered if you need time to find your feet. Be observant and analytical about it. And as with my friend from the treasury module, try to find out what the contract is and don't mention that you did not sign it. In SAP HCM module everything appears to be ok so use ESS to confirm some outstanding data and table PA0105 and PA0027 to see where the mistake was, and learn, learn, learn... :-)
