I think i can answer this question BEST, If your husband has the qualification and experience to do the job in Qatar which is mostly about experience he would get the job, If he does not have a degree the only think that would affect him would be the title on the Visa , to be honest it would not matter for a british passport holder as you get Visa on arrival anyways. When it comes to big companies most companies prefer Degree's but his experience and times as well can be something they can look at. Also depends on the company clients most big clients will require a Degree but with regards to work i dont think he should have a problem there. Thanks Hope that helped
