Your point of view towards new companies and the job seekers are very true as per the recent incidents happening in our country. It is very difficult to get a good and secure job (in private companies). As you said it is too much difficult to know which companies are genuine and which is not. No doubt, people are very much aware laws and regulations of companies act and other parameters in these days. However, newcomers may suffer due to lack of evidence and knowledge of the company's background or past histories. You can check their registered no.s via online by searching 'Registered companies under ROC of India' year wise. The registered no.s are mostly available on their certificate and/or websites. However, it is not fully guaranteed that all the registered companies are perfectly OK and make one's career perfectly. It depends upon their performance, standard and board of director' activities.
