In codility test they asked me to code in Java script. I am data engineer how can I do coding in Javascript. I know language is similar like java but the problem statement was for web developement guy. Also there was no option to change language in codility. This was not good at all. I contacted recruiter 3 times after that but no reply from them. Please its request to recruiters to be professional on this.
