Updates on the position.
just FYI :
got an update regarding my result..
My solution was rejected for the following reasons :
The code in general is overcomplicated, hard to read, and weird decisions are made
Hope it helps somebody who is interested in the position The advert for the position is still open in LinkedIn under the title : Senior C# Developer Elysian
Good LuckComment

I had a challlenge to convert numbers into words - I did well created a well reusable componentised solution in less than 100 lines. I got feedback that it did not contain any patterns. I said that the question was not worded as a check writing program or something so was rejected. Then at CME I used Factory and Strategy patterns and got shot down for being an overkill solution. Go figure - nothing you do is correct either way. But from what I heard, CME uses C# of the dinosaur era, so you're not losing out much.Comment

Hi guys,
I am on search again and probably will be doing this test again, so will post the task here so we can discuss possible solution.
See you.Comment

Been there... Ask yourself why they are constantly looking for new people?
Project managers ex startup, who thinks they are very good dev/leads so be prepared for fun ride as non of that is true.
If they haven't changed anything - it is winforms C#.Comment

Here it is: CME Vending Machine Test
Vending Machine Test – C# Developer
Thank you for your application. The exercise below forms part of CME/Elysian’s recruitment and
selection process for this vacancy.
The Task:
A vending machine sells items for various prices and can give change. Write code that models the
machine and implements the following features:- at the start of the day: loading the machine with coins of various denominations (e.g. 100 x 1p, 50 x 5p, 50 x 10p etc…)
- calculating the change to be given when an item is purchased (e.g. 2 x 20p used to purchase
an item costing 25p might return 1 x 10p and 1 x 5p)
Consideration should be made as to a suitable level of generality as well as other factors such as (but not necessarily limited to) performance, flexibility, maintainability, error conditions. A user interface is not required. Where the problem is unclear the candidate should make any assumptions that they think appropriate.
Along with the code the candidate should provide some documentation (which may simply consist of
comments in the code) describing the solution along with any assumptions that have been made or
limitations in the provided solution.
When evaluating the solution the following factors (amongst others and in no particular order) will be
taken into account:- simplicity, clarity and readability of code
- correctness and efficiency of algorithms
- class and method structure
- appropriateness of data structures used
- appropriateness of assumptions
- flexibility of design
There is no time-limit but the task should not take much more than an hour. The ideal solution will be
simple and readable, with efficient and well-designed code that fulfils the requirements.
Before you submit:- Check any of the referenced libraries are causing it to be blocked (a dll extension, PDB or
CACHE) Send an encrypted version of the zip file, which should allow the email to pass
through our mail filter - Remove or change anything that is .ade, .adp, .bat, .chm, .cmd, .com, .cpl, .exe, .hta, .ins,
.isp, .jse, .lib, .mde, .msc, .msp, .mst, .pif, .scr, .sct, .shb, .sys, .vb, .vbe, .vbs, .vxd, .wsc, .wsf,
.wsh, .rar
Post your thoughts on implementation taking in account that implementation should not take more than an hour.Comment
