Lots of questions, you began to feel used like you are not really being considered for a job just being squeezed for knowledge and current best practices and strategic ideas. I wasted a lot of time and answering 15 to 20 initial emailed questions, thena about 10 more, then traveled 40 miles round trip travel consider time to office, more questions on strategy then asked to make mock websites / landing pages for the company and explain thought process behind it and to do additional time consuming work which included looking at over 10 examples of past and current communication leads initiatives and to improve them and send them back highlighting all that was done- this all as you know takes a lot of time, so you realize he has you working without being hired and without consideration of payment or the opportunity cost. After a while you think about and feel bad and realize nothing is fair or right about that.
