Algoworks Front End Developer interview questions

This has been by far, the worst interview experience for me. The HR was really unprofessional. I'm based in Gurgaon and I got a call regarding the job opening and since the interview was to be held in noida, I wanted to make sure about the ctc before going for the interview. The HR told me they are fine with my salary expectations and that it would be a 1 day interview process. So, I took a leave from my firm and went for the interview. After the 2nd round, I was asked to come again for further rounds. So, I had to take another leave for their interview process. Before that, i again called the HR to tell her that the salary i'm expecting is not negotiable, and if they are okay with it, I'll come again. I went again to noida and gave the final round. After waiting for 4 5 days, I called the HR to know about the results. She said that I have cleared the interview but they are having TROUBLE with the ctc. They couldnt give me the salary I'm expecting. She told me she ll get back to me with the best possible offer they could give, but never called me again. P.S. I was disappoined not because I didn't get my desired salary but because of the level of inconvenience i had to go through because of their unprofessional behavior.
