My advice is NEVER to do a course with a guaranteed job offer. The reason? Simple, the course provider gets you in with the promise of a job and only then do you find out that the job is either badly paid or in a terrible school or something like that.
If a course provider helps with job assistance then that's another matter, but tying the course and the job so close is dangerous in my opinion.
Get the job yourself or through a reputable agency.
