Interview Preparation Tips

Interview preparation tips for other job seekers - Never waste in giving interview with this company. Really HR service is very pathetic. Before technical interview, they discussed about my notice period. After clearing all technical interviews and spent entire my full day by spending 1300 for travelling and food, the HR said i doubt 90 days notice period will join our organisation. Unfortunately technical interviewers are very good.
