GoTo Lead C++ Engineer interview questions

I found ad on the company's web. Applied on web - not working. Then googled up a mail address and sent CV: got call in a day, we arranged interview. Nornally there is also a written test, that was skipped for me based on vast experience (good point). The interview was supposedly technical, some talk about past projects (fair), then to implement a library C function on paper (major WTF). Light questions on leadership, zero question on C++. The guy said I passed this, but they select from several candidates and expect call in 2 weeks to have just one other interview with VP. Gor mail in a week that not selected. I'm put it at 90% chance the company is fake-advertiser, after the process I'm 100% convinced. Will check that ads will stay on for another year just as they were up for at least half in the past.
