Most of Walk In Interview in Dubai are advertised in Local Newspaper And also site like Dubbizle.but for now I guess Dubai is a bit Tough compared to few years back but in my Opinion I would advise u to go Fujairah,Sharjah,Ajman or Ras Al khaima u might be successful there but again I won’t advise u to go to Abu Dhabi as the same case as Dubai.
