US Postal Service PSE Mail Processing Clerk interview questions

Applied, took personality test, was asked to take 473, scored a 82.5 asked to take drug test and interview, met with the postmaster, he was very friendly and down to earth. At first it seemed like everything was going great, he was telling me about the job and what to expect. Then he started saying that their are 50+ applicants trying to get 4 jobs. I think being a small framed female for a job that is said to require heavy lifting, they might not think I was capable. Its been 2 days now, keeping my fingers crossed!
