Beware and suspicious of this process and only engage of you are ok with spending weeks (80 hours) working for free. Everything that is not as it seems. This is a consulting firm who is well versed in getting you to waste your time (they are used to billing for time). I don't even think they are aware of this behavior as it is part of their collective borg-like DNA (that has been codified as P-III)
Things are offered and not delivered. Respect is more then a word. It is a way of treating people.
