Applying for Frontend Job

I came across a Junior Frontend Web Developer job and after reading through the requirements, I thought "what the hey? I'll apply". I have been doing the Tech Degree for Full Stack JavaScript, but am only a quarter of the way through and sadly had to pause due to financial reasons for 2 months, but just unpaused. But looking back over what I've covered on Treehouse so far and previous programming knowledge, I'd give it a go.

But, I have never gone for a development job before, in fact, it's the reason I enlisted into Treehouse, is because I am serious about turning it from a hobby into a profession. So I want to be prepared.

The job requires HTML, CSS and JavaScript knowledge, which I think I can hit. My strengths in this regard is that I have gained a good understanding of HTML, CSS and JavaScript from here and have previous programming knowledge from being a hobbyist (but C# and not web related). This has led onto my using it where I work, although it is an admin/customer services job, I had a few ideas for our new booking system to make the process quicker and reduce errors, they liked it and I have been spending time coding it using a combination of HTML, CSS and JQuery, as well as VBA (for the Excel side of things). As a result booking errors have gone down and processing bookings is quicker.

However, I would argue at present, my portfolio is a bit weak. I have the website I've developed for my RolePlaying group, which has user authentication and is based off of Ruby On Rails on the back end, HTML ERB, CSS and a light dose of JavaScript (it doesn't make much use of it). I have the project at work. And the projects I have been doing for the Tech Degree. But nothing to show off on top of that. I wasn't expecting to go for an opportunity so soon.

In the list of "desirable" skills. There is Bootstrap and Angular, I have followed one of the Bootstrap courses here and have some knowledge to back myself up and will be attempting to go through Angular over the next few days to get somewhat of an understanding of it.

However, I was wondering if there's any advice people might have going for a Front End job? What to expect. And I will attempt to accommodate and if I don't get it, use it as a learning experience to what'll help in the future.
