I don’t necessarily disagree but anyone who is a c++ programmer and sees

    class foo { 
        public:
        foo() {
            ptr = new other();
        }

        ~foo() {
            
        }
    };

And doesn’t immediately question it doesn’t instil confidence.

Interviews are inherently high pressure situations for the candidate, the only way to avoid that is to just let people try out on the job and fire them if it isn’t working out. That’s unfair to everyone.
