Bloomberg Senior C++ Developer interview questions

I applied online, then they contacted me by mail to set-up phone interview, it took about 1 hr, the interview was with one developer, we use online coding tool where he was watching what i was writing like pair programming, he asked me to write code in C++ the task was easy but I did not perform well

I was initially approached by recruitment agency, for which I needed to do an IKM C++ test for screening. I'm not sure if this is what Bloomberg demanded of them or not. After that followed a standard phone interview with an engineer from Bloomberg. I lasted more than half an hour and appart from standard who we are/who I am questions, it mainly consisted of C++ trivia: - what is a pointer, - what is extern C, - what is virtual function, - what is singleton and how would you implement it, - what is const, - what is mutable, - stack/static/heap memory, and so on. They were satisfied with my answers so I got to face-to-face interview in their London office two weeks after phone screening. Two Bloomberg engineers met me. They were some project/team managers. They offered me coffee from their cafeteria, but I politely declined. They took some for themselves and we proceeded to an office with glass walls. One of the interviewers was fairly quiet the whole time and looked a bit annoyed, while the other one was really friendly and helpful. The friendly one admitted at the beginning that he had not even looked at my CV. He had a couple of sheets of paper and selected few questions from them. The whole interview lasted for about an hour. 1. Question: char abc[27]. char* ptr = abc strcpy(abc,"abcdefg") What are data types and values of following: abc[3] &abc[3] *abc abc + 2 abc[6] abc[7] abc[8] *ptr &abc ptr + 3 (and similar) 2. Question: Base { public: void foo() {} } Derived : public Base { void foo() {} } What does this program do, line by line: Base b; Derived d; b.foo(); d.foo(); Base* bb = &d bb->foo(); Derived* dd = &b dd->foo(); 3. Question: Write on paper a function in C++ that will reverse the order of words in string without using O(n) memory for this. So "write reversing order function" should become "function order reversing write". 4. Question: do a code review: char* addnewline(char* s) { char buffer[1024] strcpy(buffer,s) buffer[strlen(s)-1] = '\n' return buffer; } Then he was using my code review comments for follow up debate: What is auto keyword? What is the opposite of auto? Where in memory are static variables located. Where in memory are located variables, that are declared outside of any function?
