Meta Software Developer interview questions

Was contacted by recruiter through linkedin profile. Had a initial phone interview with collabedit. Was not offered an onsite interview. Was asked to write a program that would take a filename and a search pattern as arguments and return if the pattern matches the filename. Wildcards * and ? can be used in the pattern. eg: 1. filename: file.txt pattern: f*txt result pattern matches 2. filename:file.txt pattern:f?le* result: pattern matches Answer: bool matchFilename(const string& flname, const string& patter) { for (int i=0,j=0;i<flname.length(),j<patter.length();i++,j++) { if (patter.at(j)=='*') { if (j+1<patter.length()) { i = flname.find(patter.at(j+1),i+1); i--; } } else if (patter.at(j)=='?') {/*do nothing*/} else { if (flname.at(i)!=patter.at(j)) return false; } } return true; }

A phone screen followed by 4 onsite interviews. The interviews were mostly about coding which I liked, the interviewers were very open about their likes and dislikes in facebook and helped sell the place. The recruiters were great in keeping me in the loop and giving me the status and eventually the offer.
