TravClan Software Development Engineer (SDE) interview questions

Q - Closures in Javascript.

The interview was average as they ask you a lot of question from your project if you have done any other than that they are going to go for a specific language you know for eg. i know java so they asked me the questions related to java like what is JDBC, what is abstract function and classes etc. then they have asked me to do a data structure question and thats it.
