Meta Software Developer interview questions

contacted thru linkedn , if I was interested in facebook. Pondered whether to give a try or not . As my impression was facebook being php shop and me being a scala developer it would not match my skillset(Not interested in going back to dreaded c++ either). Meandered and then agreed for phone interview. I have pretty good exp (10+) most of these interviews are not cakewalks but not hard either. Only concern being absolutely neat monkey coding text book soln in 30-40mins. Most of the interviewers are nit picky and want perfect code. So you have 10 mins to think and 30 mins to code in a collabedit. Unless you are able to monkey code the soln while talking to interviewer , just simply avoid its nothing but sheer nonsense. But if you want to practice then ;-)
