Trending @Infosys; What is the possibility

Hii everyone, Today I gave my last round of an interview in which interviewer asked me about my current company project work and all ,I explained him,then he asked 2 coding questions of dsa both of medium level. Fir question I wrote complete optimised code but for 2nd one I can write only brute force not complete optimised. Is there any chance that I can be selected in that last round?????
