Synechron Senior Nodejs Developer interview questions

I was eagerly looking for Pune location opportunity and had applied many time to this company. Luckily I got a telephonic interview scheduled on weekends. I prepared my self very well and the interviewer started with very basic questions first and after moved to some advance concepts, which wasn't tough for me and felt much better than satisfactory performance from the interviewer's response. Overall, telephonic screening went well and I got the update from HR about the further upcoming rounds during the upcoming weekends, but I didn't receive any call from the panel. I tried connecting with HR and sent mails got delayed response saying it will be scheduled in the next week. The same thing happened next week. I was really disappointed from such behavior. I was positive about the upcoming rounds. But don't understand why such ignorance though being quite matching for the job profile. Didn't even receive any single mail after that! Such company's HR needs to work the human values! I won't be appllying/joining this company even I get an offere. Such behaviour reflects their culture.
