Words of Advice

“Don’t be discouraged if you don’t get interviews or offers right away.  You may, but sometimes there are automatic filters or non-technical recruiters who filter the wrong resumes.  Additionally, they may be looking for a specific type of person, quiet/talkative, funny/boring, personable/professional, that has nothing to do with skills.  If you are passed up because of this, it may be a good thing, because you want to be able to fit in without changing too much.  Keep in mind there are new jobs opening up all the time.  You want to present yourself as excited to join the company, not desperate to find any job.” Scott Ishida, VP of Information Technology
