Our automated test tasks are based on industrial problems. They are designed to evaluate your readiness for professional positions.
High performers can get access to top-tier job opportunities. Beginners who have enough skills can prove it and turn a hobby stack into a professional position!
∅hr uses specific and concrete performance metrics to evaluate your skills against real-world problems, such as measuring I/O throughput in big data processing tasks and clickthrough rates in ad campaign optimisation tasks. The submissions are run in docker and the results are statistically compared against the reference solution ran at the same time. If the deviation is outside of the acceptable range, we run submissions again until we have the confidence in the scoring.
First you receive a task specification and instructions for submitting your solution. Once you submit, your solution is queued for running and ranked within a few hours. You'll receive a score sheet as a candidate, with a chance for a second attempt if needed, and companies receive an evaluation sheet. If you don't receive a good score on your first attempt, you'll be informed and given a second chance, with access to some simple data samples from the tests.
I was open to taking the ∅hr test as the technical interview for Yatima Inc. The only things I was concerned about were the clarity of the task and the time required to complete it.
While solving the task I found the presentation of the task to be exceptionally clear. Time required also proven to be a non-issue, owing to the fact that most of the surrounding code was provided by ∅hr, so I could concentrate on the essence of the problem. The ∅hr test task was really well-presented and, in contrast to whiteboard interviews, used a deterministic scoring method with clear criteria. Additionally, I appreciated receiving the TeX source of the task description alongside the PDF, enabling me to conveniently copy segments of it into my comments and code.
I utilized both attempts to submit a solution and was reassured that it's okay to submit an initial solution that might not pass all tests flawlessly. In fact, in my initial submission, I have overlooked a nuanced detail in the specification. Thus, both the feedback after the first attempt and the availability of a second try proved invaluable in refining my tests and ensuring my final submission was perfect.
We are just exiting the stealth mode. It's a perfect chance for you to stay ahead of the curve and get early access our tests.
