Don't put your full effort into it if you don't think this is really the job for you because they will seek out of you're the right person through many, many, long interviews. I had a positive experience with the first three interviews, then the last one made me not want to work there anymore. The first two were very conversational and welcoming of questions which made me more interested in working there. Then, the last one was a very difficult interview with the type of questions being asked and the interviewer. My interviewer even answered a text in the middle of it, which I viewed as very disrespectful of my time. They will have you do a designer test for this role which will take up a lot of your time, in my opinion -proving as a pre-curser to how it would be to actually work there full time. Other than that, the communication on both sides was pretty good as far as being transparent with how the process will go. Only advice I have is don't put any effort in at all unless it's going to be your full effort because they will expect this of you just by submitting an application!
