Well I got this email today from HR. I guess that answers my question on hiring for now. I guess things are very fluid at United!!

Dear Pilot Candidate,

As you know, you are currently scheduled for an interview at our Training Center in April.

We have just been informed of adjustments in our Training Schedule and have found it necessary to indefinitely postpone future Pilot New Hire Training Classes. Therefore, we are canceling all scheduled interviews at this time. We are very sorry for any inconvenience that this may cause you.

United, along with other U.S. airlines, has been managing to remain competitive in a difficult environment. However, we’ve seen a rapid escalation of fuel costs over the last six weeks. This, along with continued uncertainty about the overall U.S. economy, has put significant pressure on all U.S. carriers.

You should be receiving a phone call from someone on our staff to confirm your interview being canceled.

Once again, we are truly sorry for any inconvenience this may cause and appreciate your interest in United.
