Once you do make it to a lab you can expect an entry level job, not chief physicist.
Just like after I have finished all my training in aviation, I should expect an entry level job flying, not getting a job as the chief pilot! Also, not an entry level job washing the managers car (which is what I did, and was paid for when I was young and stupid!).
I have spent many hours on the hot tarmac washing airplanes and vaccuuming the office. I am sure it did wonders for my attitude, but I fail to see how these cleaning activities made me a more proficent aviator!
