Interview Preparation Tips

Interview preparation tips for other job seekers - So, total 2 technical rounds was there followed by 1 managerial round.
Everything went well. After this, HR round was there asking about the expected salary. Everything is well till now.
But when I got the mail for the sample compensation plan, it was quiet low as expected after all the 4 rounds of interview. And surprisingly, HR wasted total of 25-30 days in the whole process.
