BNP Paribas interview questions

Had a phone interview and a face to face interview. Interview was competency based and it went well. The company had stated before any offer is made they carry out a credit check etc and that I should hear back in a weeks time. Been three weeks and no offer or feedback.

applied for the job on glassdoor(redirected to their website), got an email for schedule on site interview(in Montreal), and went to the company for behaviour and some security question, overall i performed poorly over the interview (did not anticipate it and prepared for it as much as i can), i was too optimistic about the position.
