Teletext interview questions

There were 3 rounds. The first round was by Sr Architect; he asked mainly scenario based questions, logical question, and few design pattern/architecture related questions. The second round was with CTO, he just asked about my experience and recent achievements and the last was HR round.

got a call from Teletext and they told me that my resume got shortlisted and will be scheduling interview call. First round was telephonic, second was Skype interview with the UK account manager and the third was in person interview. The whole process took 1 month and after two days of the final round, I got a call from them and they said that I got selected and the offer letter will be released soon. The next day they again called me and said that I will be receiving a reporting task in next two days from the account manager and if I completed that task then only I will receive the offer letter. Days, Weeks and Months passed by, but I did not received the task.
