I have given the interview. After that, they selected me and asked for Documents sharing. I have shared all the required documents. Company recruiter told me that he has reviewed my documents. Then, they have done the salary discussion. They asked me for Resignation mail without sending any offer or appointment letter. I have shared the resignation mail to them without any offer letter because company recruiter was saying that offer letter will take time to generate that's why I trusted them. After that, Their behavior suddenly changed. They are not doing any communication even they are not picking my phone. Recruiter who was communicating with me since 4-5 days and when I called him he was saying on the call that he is behaving like he does not know me. Note: Please be aware from this company. Don't trust the recruiter of this company. Be careful.
