There are a variety of project management methodologies. Important for project managers to be trained and useful in any capacity (i.e. technology project management, agile, Prince 2 etc.)

In essence, seemingly before applying for a job at a company PMs should think about doing some research to find out what project management methodology that company is currently using. (hint).

In the state where I live, Agile project management is becoming the most demanding. Therefore, since I have downtime due to a layoff, I am currently in the process of registering to go through Agile training and take the Agile exam. Hope to complete by end of year 2013. Wish me luck!
