In the process of applying for a job with another company. It all looks fairly promising, but...

... they use SVN for source control 😫

I have a job where we're currently using ClearCase SCM and from that all I can say is that as long as they have a good process for the tools they use I don't think it matters that much.*

*I recognize it is important for certain things you might do day to day, but I wouldn't pass up a job I was interested in because of the source control.
