LetsMD Senior Software Engineer interview questions

I put three rounds for Senior Software Engineer position and they all were in different days, one was telephonic and two were face to face after completing the third CTO round I was wait two days for feedback but HR didn't send, then when I did call to her so she pretend like she don't know me and behave like a foo* that I haven't receive your feedback from CTO yet. I believe they are in illusion that they operate Google, while the entire company will fit in a egg shell. In simple words, it just waste of time and day. probably they are looking for some cheap ( 20k month ) developer but not hesitate to wasting a Sr Dev time. Cheap People. I am highly recommend don't waste your time to put interview in this company, cuz you even not will get the feedback from these googlers.
