True Digital Communications interview questions

Interviewed by an HR rep that was kind and asked good questions. Easy to get to next interview. My experience was well within the requirements. The next interview I prepared examples, dove into relative experience, and felt incredibly positive about the interview. I didn't hear back and had to follow up severval times within the next couple of weeks. The hiring manager gave me no real explanation other than the canned response. I finally heard from the hiring manager who gave me feedback that didn't make a lot of sense. I felt like I dove deep into the position but he wanted to hear more. The training for the position was months, I learn fast if there is something I didn't know, I could learn quick as everything in Marketing. I don't agree with the hiring manager's assesment of the interview and am frustrated with the outcome. No real reason other than someone explained Google Analytics tools better. I came prepared, and left absolutely perplexed. I feel like people who interview especially for these companies, need to have a better approach not expecting the world but seeing potential.
