the qatar job is genuine - BUT... Aw years ago several colleagues of mine went to wotk for thi same outfit. they worked for 9 months and were NEVER paid - they constantly received promises, reassurances etc etc, but NO money. After between 6-9 months they all returned to the UK having been paid not a peeny. RThe outfit concerned (the same one you mention) said that they wouild be paid when it was 'good and ready' and that if they made noises they would be out of a job. Don't trust them as far as you could throw them.
