Reverie Language Technologies Software Developer interview questions

They gave me task to complete within few days. After submitting the task I had a conversation with the interviewer. He asked me about projects and networking concepts and he modified the same task with more complexity and this time i was not able to do it. Then i had a telephonic conversation with hr and after that a final tech interview was conducted.

3 rounds, 2 tech, 1 HR HR round was first (strangely). Normal HR questions were asked like "Tell about yourself", "Your goals" etc. 1st tech round they asked questions on your resume like stuff abut projects and the areas you are strong in and some puzzels. 2nd tech round goes a little deep into the topics
