I had an interview in December last year, and it took them 6 or 7 weeks to get round to telling me the result.
Have any rated 737 FOs been interviewed yet?
Is the contract recruitment being handled by Zenon Recruitment by any chance? I noticed on the FLight Global Jobs site that Zenon are recruiting for 737-300 rated crews for a UK airline with several UK bases. I doubt that it is BMI Baby, the only other operator of vintage Boeing metal.
