I had a call with the HR for 30 mins. A second round telephone interview was set up the next day. I have 30 mins of pretty casual conversation. A little bit on experience, nothing specific but the response was very positive towards the end of the call. I sent my Thank you note and requested for a courtesy feedback. The least the company could have done is follow up with a feedback for time and interest I have shown towards the company. It's been 3 weeks and It's quite shameful that companies of this caliber take people for granted and don't have the basic courtesy to follow up. Shameful!
