Cisco Software Developer interview questions

First, I was contacted by the Director of engineering asking for the time to schedule the interview. And I was scheduled for a Cisco Webex interview with 4 of the engineers in the team 45-60 min each back to back. Every interviewer was nice. Second, I got the mail from HR saying that they want to continue with me in the process and make an offer and she will contact me for further process. I waited for weeks and then mailed her regarding the further process, she replied that she will get back to me in a day or two. But I never heard anything from her even after following up with her several times. Then I directly followed up with the Director of engineering of the team as It had been almost a month that I gave the interview. I got a reply saying that they are unable to make an offer at that point of time as there is a budget issue for the team. I felt very shocked by the response, why do they even say that they want to continue with an offer before knowing their team budget. I lost some of the other opportunities that I had in between this one month of the period. I never expected that the reputed companies like Cisco would treat their applicants like trash.

It was a 3 round interview process.1.Technical Questions (Core java, spring, Hibernate, Database) related 2. White boarding - Coding round 3. Generic questions regarding your previous experience and How would you deal with real time problems
