INTERVIEWER

Interviewer

Um, Let me, let me try a different question. Specifically, this is, this is definitely one of my favorite product manager questions. Um, what is the most complex system or product you've ever had to design?

CANDIDATE

Candidate

Oh, OK, to design or to be involved.

INTERVIEWER

Interviewer

That that you were responsible for designing, not that, not that you participated in, but that it was like, OK, this is my, this is my original thinking and, you know, this is what we should do.

CANDIDATE

Candidate

So I, I'm going to touch on um the, the experiences I had um over the last year that I worked on kind of with myself, um. In terms of the e-commerce, uh, setup that I made, um, which was basically an area that I, it was kind of something like I, that I, that I created for myself to kind of dabble in, learn some creative, uh, to engage in my creative side and kind of learn the, the digital skills that are, that are necessary. So that involved, um, Creating, er, you know, creating digital videos, which, which are compelling enough to, to drive a customer to click on, on the, on the video and then on the link to land onto the website. Um, again, I know, I know you're talking about design specifically. I'm not sure if you mean, so, well, OK, I can also refer to the website itself, for example. So the, the website, of course, was completely my design, um, taking Photoshop, um, To, to its limits, or to my limits of Photoshop, um, making what, making the story that I want to portray, er on Photoshop and then putting that onto the website, for example, um, So, so yeah, the, the, the website I would say was, was a place that I managed to implement my design, and that design was a reflection of the story that I was trying to build, and that story came from the kind of the why, the how and the what of my brand, which came through an iteration um of, of, of different attempts between what the market might be, what the product might be. Um, so yeah, that, that's how I ultimately reached the design. The design that I reached with the website, um, and plus, and, and thus the design of the ad, the ad angle, the kind of language that I approached the, the, the ads with. Um. Yeah.

Interviewer Insight

these answers continue to lack details and depth.

INTERVIEWER

Interviewer

So what made this so complex?

CANDIDATE

Candidate

Um, so, so this, this, this wasn't, um, so sorry, it wasn't necessarily the most complex, it was just a place where I actually was able to take a complete design, um.

INTERVIEWER

Interviewer

You're saying there was, there was nothing complex about it.

CANDIDATE

Candidate

No, absolutely, there was, there was, there was complexity, but I'm, yeah, absolutely. So I mean, the, the obviously the the complexity here is. Is bringing everything together. So it's, it's making it all work together and, and for me that was a very iterative process, because I started with the design of the website, but does that, Does that match the story, for example? So whilst the design was something I learned, and you can learn it quite easily, the skills, you put them onto the website. For me, the most complex part was matching that with the story, with the why, the how, the branding, so that everything fits at the same time, the same, to the right people, with the right product. So I, I felt like that, that. Uh, those levers, those, those different levers, getting those right at the right time. Was the most difficult part.

Interviewer Insight

this answer did not touch on the question asked. The question specifically was looking to talk to a complex design. Building a website is not that.

INTERVIEWER

Interviewer

And so if you think back about and think about the the totality of the work and everything you had to do to make this come together. What was the most technical obstacle you had to overcome to deliver this?

CANDIDATE

Candidate

So there was a portion of it where I. dabbled a little bit with coding, uh, I haven't necessarily done any coding before apart from a bit of math lab in, in university, um, but there was, there was some level of coding which I, Tried to add onto the website, um, and managed to do so, and in some cases, obviously there was a lot, there are, there is a lot of content on YouTube, there's a lot of content online, but in some cases you, I, I get the base of the code, and then I might try and ever so slightly change. If it's the color, if it's the height, just don't CSS so. Very basic style, but it's, it's something that I definitely haven't done before, for example.

Interviewer Insight

again, no depth in the examples. Suffering from poor structure, and the level of technical sufficiency demonstrated was low.

INTERVIEWER

Interviewer

OK.

CANDIDATE

Candidate

So.

INTERVIEWER

Interviewer

Um, let me. just out of curio, I'm curious, what was the, what was the, the content management system or the underlying framework that you use to build this out?

CANDIDATE

Candidate

I was on Shopify. It's on Shopify, OK. Yeah. OK.

Expert Assessment

Interviewer assessment - would be used in a hiring meeting

A recurring theme throughout the interview was a lack of detail in the answers. In this particular answer block the candidate not only failed to answer the question - as it specifically regarded designing a complex system - the answer provided lacked any semblance of detail that would allow an interviewer the ability to determine that the candidate had exceptional abilities with regard to complex design.
