Atos Senior Software Developer interview questions

The interview is two folds, there was an on-site interview about my technical background and a Skype interview with the HR department. The technical interview was spoken only, and was mostly focused on my past experiences.

3 Technical rounds 1 HR All of this processes completed in a single day. But the worst part is that even I got selected in all the rounds yet not recieved the offer letter and its been more than a 6 months. In initial days I tried to reach them multiple times by mail and mobile but no one has replied. I asked my friend too to check with HR and the response from HR was, we will release offer letter in next week. Poor management and process.
