I was actively searching Job Opportunities and randomly applied to Silicon Interfaces not knowing about their deeds. A telephonic round of interview was set up sometime around 10.30 am, I didn't give a confirmation though, they kept calling me again and again and again, I was busy and sent out an email to reschedule at 5.30 in the evening and same thing repeated, finally I did answer. First of all I have no prior knowledge about HTML 5, I started going through the tutorial on tutorialspoint 30 minutes prior to the Interview and went for it. I knew I screwed up but then the next day I got an email saying we can move forward. Something seemed off, then they asked me to send an ID proof having signature, I sent Driving Licence, he asked for one more ID proof in return saying the signature wasn't clear and government ID is mandatory to draft NDA (Non-Disclosure Agreement). Note: They won't be disclosing salary unless you sign NDA. Never fall prey to them.
