White Clarke Group Fullstack Developer interview questions

After fist call with recruiter, I had a phone call with Technical Manager. Call was about overall technical topics and some visionary things. Then I got an technical exam about the Anagram algorithm. I wrote a java application using testing framework and some injections. Logging and documentations in it. Finally I got an face to face interview with two different department leaders. From frontend and backend. Unfortuneteley I failed. They were kind and positive.
