I am one of the past consultant worked here. It has been long time since we left Doon Tec, and even today blood boils when hear the word 'DTI'.
They act smart but they are not, they play around all legal tricks, but they don't invest this valuable time to make client and grow firm, they don't have any good client associated with them, nor do they have any good consultant :(
Symptoms which your wife find when you join this company
sleepless night
no job and by luck if you get than also low wages as they don't have good direct clients
late salary and bad living standard in US as they pay you less in market.
They lie you too their best and make you feel they will help you at every step, but ones you join them they start showing their original face. And by mistake after working long if you ask raise in salary they give you good convincing reason, see we also need to money... work sometime and we will take care of you, are you happy now?
