Interview Preparation Tips

Interview preparation tips for other job seekers - Waste of time!!!
They took 2 rounds within 2 weeks, all goes well. after that HR confirms that you cleared the round and someone will call you for a final discussion. Post that they never reply. and when you call back to HR every time he says "I will check and let you know" but never ever did it for months.
Don't waste our time if you are not serious about hiring.
