Prospecta Senior Java Developer interview questions

TAG HR called me one day as she found my profile from the job portal and communicated with me for at least 30 mins to know about my tech stack, salary expectations and my current role and responsibilities in the current organisation. Then she proceeded with the interview process. After clearing all the interview rounds HR called me and discussed again on my salary expectations and asked me to share the documents. Since I already had 1 offer so I put my expectations accordingly (as per the discussions we had initially) Now to my surprise HR stopped answering my calls as I was trying to reach out to her to know about the progress and the after 5 days I am able to connect to HR and she said that the we can not proceed with your profile as you don't have much experience in Microservices. Now I am a bit surprised at that moment as they didn't mention that Microservices is a must for the profile applied. I feel bad as I have wasted my critical time with this kind of company.
