Kogan's Hiring iOS Developers, But This May Be The Clincher

As I'm writing this post, my job application has been rejected by one of the most reputable online shops in Australia. It was a short journey yet I gained some insight into how jobs can be presented, and how they may not be what they seem.

Here's the job description:

IOS DEVELOPER 

Kogan.com is Australia’s largest online retailer. We use technology and digital efficiency to make prices on the latest products more affordable for our customers. Tech is our thing -  we love using it to solve problems.

WANT TO GET INVOLVED?

Email dev.jobs@kogan.com.au with the subject line [IOS-201704]. Ensure you tell us why you’ll be great for the role and you supply examples of previous work (including apps that you’ve been a part of).


You may have noticed the ripper at the end: "Experience with the following languages and/or working in an agile environment previously is a plus: Objective C, Swift, Javascript, Python, Django, React Native, Android App Development.." This isn't the kind of description you would typically see in an iOS Developer job listing, at least not for native development. I have personally never come across an iOS Developer from Kogan.com, but I do know someone who has worked there in a previous job -- the team is cross-skilled.

I applied, and to my surprise, they sent me an email telling me they're impressed with my skill set:


Hi Rex,

Thank you for applying for an iOS developer position with us. We've reviewed your application and we are impressed – congratulations!

At this stage of our recruitment process, we give candidates a quick coding challenge to let them show off their coding skills. It allows us to get a bit of an understanding of some aspects of your coding style.

Here is your link to the challenge: https://kogan-recruitment.herokuapp.com/challenge/8738436f17b6c50686b29f71198233ff/

Please complete the challenge and reply with your solution attached by Sun, 7 May 2017 23:59:59 +1000.

Have fun coding!

That link has since expired, but I can describe the challenge as having to calculate the cubic weight of items under the category "air conditioners" from a list of miscellaneous items, and getting the average.  The data comes from a JSON string, have a look:

You may have also noticed that it's paginated.

The cubic weight = Length x Width x Height x 250

To solve this challenge, I either had to write a command-line application or a web application. Being a polyglot myself, I wrote it in Python. If you would like to see my code, you may clone it from Github:

Long story short, they got back to me after a few days:


Dear Rex,

Thank you for applying for the role of iOS Developer at Kogan.com.

I regret to inform you that at this stage we will not be proceeding with your application as we did not feel you were best suited to this role. Please note that due to the high volume of job applications that we receive, Kogan.com is unable to provide feedback to candidates in regards to their applications.

Thank you for the interest you have shown in Kogan.com and all the best with your future pursuits.


I can accept rejection, I've had lots. I received no feedback though I asked for one.

But the surprising thing for me is that there was not one bit of iOS or even Mac concepts in that test. This would have turned off a lot of dedicated iOS developers applying for the job at the very beginning.

So what were they actually looking to hire?
