Want to support SQL Server ?
Microsoft are recruiting SQL Server support people. https://careers.microsoft.com/JobDetails.aspx?ss=&pg=0&so=&rw=1&jid=21950&jlang=EN
This job isn’t about understanding TSQL its about understanding programs, SQLServer.exe is a big program and you will need to be able to debug it to get to the bottom of you client support calls.
I’ve spoke to Bob Ward about the type of person that is needed and its not your enthusiast, you have to understand code to a deep level, probably include networking to debug those kerberos and authentication issues.
If you think you are up to it, why not apply. I for one would love to get my hands on the sqlserver.exe code but alas I’m not clever enough.
