I can't believe what i did. I just blew a chance any chance i had at getting my dream job or any job it seems like for that matter. I emailed that principal again and she said that my online application did not include a certification so she was unable to consider me for interviewing for the position. I sent my resume in the mail to the school (with certification on the resume), i emailed the principal multiple times and stated that ii have a master's degree and teaching experience and all because i did some stupid, careless mistake and did not check off the box to fill in certification i don''t even get a chance to interview. I feel so stupid and hopeless. how stupid of me.
