Version 1 NET Developer interview questions

Got contacted by version 1 recruitment team. The process was going very smoothly. First phone interview, then I had an interview with two engineers. After that I had an interview with HR. Everything within 1 week and half. Recruiter called me back with a positive feedback after each interview. Few days later, the recruiter said that they couldn't make an offer due to hiring manager being away. A week later he call again to tell me that they are interviewing another candidate. I said fair enough. A week later the recruiter stop replying to my emails. Finally after nearly 4 weeks he called my back to let me know that they have fulfilled the position internally. Absolutely joke. This company lack of professionalism. Wasted my time and took some annual leave days to be available for the interviews. Please avoid this company at all cost.
