It is a totally different experience for me. I don't had any experience. I was struggling for a job. But I gone there for walkin of Sr. Software Engineer. So the HR executive denied me to get in firstly. But I convinced her to get in. then she asked me to hav a test first. So i had test alone there. It's totally coding test. and I done well. after 10 min w8, I was called for interview. and in interview it's 2:1. was awesome. It's totally about the deep knowledge about C/C++ language. I done well there too. I was not able to give answer of one typical question only. But after a long evaluation n discussion b/w them , I received finally a offer letter for the SE.
