hmm... well, I guess I stand corrected by a comp sci major on this technicality. By the way, just as a point of reference, comparative lit majors are always open-minded, intelligent, witty, charming, and good-looking.
I'm a computer science major and even I know when to use square brackets to indicate that I am annotating the text that I am quoting. I.e. "...our specialty, [but I was] denied..."
Tuomoks is using a compressed form of communication that may be beyond the capability of some engineers. Here's a rewrite for non-lit majors: "I was asked to (join) one (industry consortium), (that focused on) our specialty, (but I was) denied - (even though) a manager wanted (to do) that (ie, join the consortium), they (upper management, presumably) didn't want him (to participate)! So, (the) next candidate (for the consortium), (who came from) our competition in same city of course (,) made some small changes (in the industry standards). (These changes) Did cost us 6 man years (of) rework, (in addition to) at least one lost customers (typo? should be singular) and I don't know how many prospects!"
