Such bad attitude won't get you anywhere. This kind of language by a professional is not expected. Good for the company that they didn't hired you. Thumb rule when going for interview always research about the company you are visiting. Shouldn't have high expectations from a startup or small companies. Reception area, seriously ?? That bothered you. I am sure without an interview it is quite difficult to judge the skill levels of a person. And if you were not shortlisted your skills must be below expectations. Get real. Dumping your frustration online is not the wisest thing to do. Couldn't stop myself from replying to your post. Less
