Staples

I used to work here at staples pleasant hill, 94523 as a technical associate but then I went to India back for 4 months when I came back to the US I didn't have my job so my manager Renee said to reapply at staples which I did and there was Now hiring board at staples store but when I went for the interview manager said that they didn't have any positions. I don't know that if there were no positions available then why did he said me to schedule an interview and why there is now a hiring board in front of the store
