What is the best advice you could give someone during their first month at Hitachi Vantara?

Look at leaving, however, make the most of it and work towards gaining as much out of it for your next role outside Hitachi. Most of the good people have left recently including senior management as that part of the business is a minor line item on the balance sheet for corporate. If you are in storage run for the hills, the cloud is where it is at.
