We’re now accepting international applicants!

what is the difference between this post and the last one?

I believe the difference is that they’re now accepting people outside Canada, as said in their comment #2 here.

Dimitarvp is correct. We are now open to international applicants. :slightly_smiling_face:

i applied in the last post, i need apply again?

Hi Nicol! I have your resume, so no need too. Your all good!

Out of curiosity, what’s the technical interview like? Take home or Async?

It would be a take home where we give you one week to complete, and a systems design question which is done during the interview.

Is a take home the only option?
Have you considered alternatives such as just being able to review someone git repositories?

It feels really unfortunate to have to be vetted and also hope to aline with a company because of what can feel like an esoteric quiz when the company could have satisfied their inquires just by reviewing the applicants already created code.

I personally will just reject applying for positions that ask for a take home because I already have written enough code for some to read if they wish to see the best and worst of my abilities.

I would bet I’m not alone in this feeling.

None of this was to be critical of the opportunity you are providing for the community.
I just wish the hiring process was less redundant and wasteful of the applicants time.

There is already a huge risk in investing your time just applying and interviewing let alone a week long task that is on me to do in a vacuum only to not get a job in the end.

Thats just my 2 cents.

I am pretty sure that the task would be for a few hours of coding but you have one week to send them the solution. :slight_smile: Or at least I hope. :grimacing: :sweat_smile:

The, “lets give them enough rope to hang theirselves and see if they only spend 1 or 2 hours on a thing that we don’t want back for a week but will also be a critical part of the over all choice” is a cruel thing to do to applicant in my own opinion. It also does nothing to address the redundancy of the act in the first place. Again what about all the code I’ve already wrote that is already public and accessible?
Why is that not sufficient enough?

How about you got a whole week to read my repos and get back to me?

Sorry this is too big for here, and I don’t want hijack this post. I do think its worth asking though.

I mostly agree with your opinions. I just wanted to clarify, that being given a take home coding challenge that takes 1 week of work would be unrealistic.

We’re just giving enough time for those applicants going on vacation. For experienced applicants doing this challenge it should be a breeze.

Please let’s not hijack jobs offer.

You can open a chat/discussion for … discussion :slight_smile:

Sorry I was just simply asking if there was a alternative. Though I have not got a reply.
No more on that needs to be stated.


Couple of questions:

  1. Is Catalyx open to hire freelance developers?
  2. Are there any timezone overlap requirements? I am based in Europe myself.
