First alarming signs were already present in the job description: company demands very high level of technical skills, but salary offerings are not that generous. But I decided to try since there are not many technically advanced companies out there, right? Nothing special overall for 1:1 meeting: regular marketing talks. But it also raised second alarming call — I personally don't think that IT professional and modern Internet activist could call the way how company earns its money — truly honest one. Third call was the coding challenge. They gave me deadline of couple weeks, rather than test my knowledge in the office right away. Thus, I had all the time I need to make code perfect, test performance, internet access to search for answers, and literally no stress! I completed it during weekend using two different approaches: object-oriented and functional. And they dropped me even without reviewing second approach. No hard feelings, even 15 years of experience could potentially lead you to failure, but interesting fact that they was not able to provide any constructive feedback on the assignment. They admitted that decision is subjective. And what any feedback will hurt their further recruitment process. Although I would say lack of clear and open communication will definitely ruin any relationship. And better to face it early stage, than find out that you didn't pass probation period and you don't know why. Or you denied promotion "just because". And so on. I would say it's company to avoid, if other options are available. Theoretically it could be good place to get some battle experience and move on, but I will never know for sure already.
