I think your portfolio could use a lot of work. The forms that you have chosen don’t always follow the function or match up with your target market, it is much too wordy (no one’s going to read that stuff), and the projects seem a little bit under-developed in general. I would strongly advise reading some of the more granular feedback that a few of the others gave. They were very helpful.
Besides having a baseline skill level as a designer, the other important factor is just developing a rapport with your interviewer. This is something that is impossible to evaluate over the internet. Things like posture, elocution, and overall body language all play a role. A good rule of thumb is to be come off as eager to learn and confident, yet humble. Err on the side of humble if you’re going for entry-level positions. If you seem overly confident, managers will see you as a threat and not feel as inclined to hire you.
