I enjoyed very much practicing algorithms, getting to know companies through the challenges.
It is a well organised, polished platform for coding skills evaluation. The lessons and challenges provide good content for user practice and the summary section helps to understand the areas the user is going well and areas to improve.
CONSThe platform suits me very well so I don't have any comments on things I dislike or wish to improve.

Coding for Technical Assessment
Codility is very easy to setup and user friendly. And one of the few things I really liked is that, for the monthly plan, the number of candidates to add for assessment is unlimited unlike other platforms that would usually have 30 slot Max.
CONSCan't really think of one, its a great tools for company that hires Tech talents in volume.
Reasons for switching to Codility
Its was quite pricey.

Not an adequate test for most engineering roles.
If you use it, I would suggest the live-code feature where you screenshare and watch the applicant solve one larger problem, preferably one that relates to the job at hand rather than a mensa puzzle. Make sure to review the failing submissions because in many cases, they had it right, but the machine graded them wrong, this could be for many reasons including the structure of the training set they were given was different from that of the testing data. Over half of what our engineers do is debug, interpret existing code, and build infrastructure. None of these things are tested with Codility. If they do pass, they are proficient in at least one element of the job, but not necessarily the rest. I interview any applicant who passes with 30% and always look at their code even if it failed.
PROSIt is deployable and easier for HR who don't understand code themselves. The ability to compare to other programmers' skills is nifty.
CONSMany of the problems are not completely presented (I.E. there are other factors that are not mentioned which would influence the code, so applicants who submit overly-thorough code will actually fail because the machine didn't like their answer.. it is a guessing game) 20 minute time limits to solve an algorithm problem are NEVER the case in real life. Programmers do not work off memory, they work off documentation-- codility does not test on use of frameworks or libraries, only math concepts. The IDE is limited, will delete the applicant's code if they switch languages momentarily.
Reason for choosing Codility
Pricing, ease of use.

A great developer assessment tool
Codility has helped me improve my skills as a developer and as an employer, I use Codility to frequently keep my staff sharp on the job by frequently testing their capabilities.
PROSI have used Codility as a developer as well as an employer and I can tell you that it is a great assesment tool. One of Codility's key advantages is that it enables employers to quickly and effectively assess the coding abilities of numerous job applicants. Candidates can work at their own pace through the online coding tasks on the user-friendly website.As a developer, I use Codility to assess my coding abilities and learn new programming paradigms in the process.
CONSSome of the things which I would like them to work on is an offline mode. The complete dependence on the internet may limit some users from enjoying its features. They should also make it such that tests are optionally timed, many times, developers are not able to complete the tasks within the short timeframe.
