Be calm, i was interviewed in lag yestaday and am still serving,i got around to ask my interviewers and they emphatically told me that my status will not be prejudcial to my sucess at the interview, urs is even beta,am finishing service by october. go for it guy and u l be victorious,amen.
d interview is rili not a big deal,know abt 1st bank and banking generally,they want to know weda u av passion for banking and let ur current affairs skills be at 100% level,topics like deregulatn,resource control,EFCC, ETC may be thrown ur way to discuss stage1 group interview, while u may be asked ques on bankin and 1st bank on ur 1-panel 2nd stage interview.
ALL d best!!
