It's the first time I wrote a review about interview. Because I even decided to stop this disrespect and left it. This was the worst interview I ever had during last 10 years and during last week ( I had about 5 interviews total with 3 offers), a classical bad interview. Company is not friendly; candidate is a body for mockery. This is a bank software. But an interview where guys with prepared answers on their side start to stress and confuse and tangle the candidate with deeper and deeper questions about the topic and syntaxis. If you are not an interview cracker, but have large experiences and wide knowledge, even if you've learned several books like Richter, Fowler or Troelsen, write good code but doesn't "rotate red-black tries on paper" - this is not for u. Sorry, guys, there is a border and big difference between how candidate resolves algorithmic tasks and thinks about problem and how he compiles your paper code with errors in his mind under pressure and dozens of reference questions which try to confuse more. Especially when you never develop this way, while know that it's a bad practice. I strongly don't recommend to take a part in this party, not to allow them to cherish their sense of self-importance and power over the candidate. The worst thing was then I felt the way of discussion after the first questions and just said, that development of compilers or languages is not my duty\fun and I never wrote about it in my resume. If you need knowledge deeper, then Richter provides in his book, then I'm not your guy, lets don't spend our time. But they said, that everything, called it "we want to know how candidate thinks" and continue that sh*t. What could be done better? If candidate doesn't fit your needs, then don't continue to ask him questions which will force him to fill like flout. Leave it, talk about life and then send "Sorry, not this time" via email.
