Verizon Software Engineer Intern interview questions

I applied on their website which I found out they were hiring through indeed or monster. After that, it took between 1 month and 1.5 months before they contacted me for an interview. I went through 3 interviews. The first interview started with technical questions from a senior developer. The questions involved stuff from Databases terms, like inner joins and outer joins, PHP, CSS, HTML. The intern position was to help with a web application. After that was done. The second interview, I was contacted by the manager of the project. He asked questions that help him learn about my character, work ethic and to figure out if i will fit with the team. After that I was contacted by an HR person where I was interviewed and then notified that they wanted to hire me. Each interview lasted more than 30 minutes and no longer than 75 minutes. Overall, it was a great process and they were very professional and great to talk too. I took to long to accept the offer because I had other offers and were waiting before I decided, so they rescinded their offer after 6 days. ( a bit short but whatever, I have options) Note: I asked the HR lady why I was not interviewed in person and she seemed confused for a bit and asked me a second time if I was really not interviewed in person at all? I said yes and she said well the manager was probably out of state or very busy.
