Dolphin Technology Digital Circuit Design Engineer interview questions

I applied online and a few days later I got an email inviting me for an onsite interview. Strangely they skipped the phone interview and I though it's because my resume was looking good enough to them but I was wrong! As it turned out later they even hadn't looked at my resume. I wasn't living in San Jose and the email clearly stated that they won't reimburse travel expenses. At the beginning I was hesitant to spend a lot of money to book a flight and hotel to go to onsite interview but later I thought it might be worth it if I get the job. The interview was on Friday afternoon. There was no schedule or plan of any sort for who should interview me and when. The HR just selected two junior engineers on the spot to interview me. It was obvious that they were not prepared to interview me and they had no idea what is in my resume. Then a senior engineer showed up to interview me. The moment he looked at my resume he told me that I don't seem a good fit to the job and that they are looking for someone with more transistor-level design experience and less RTL design experience. I liked his quick and honest feedback but I also got very annoyed that why they didn't check my resume beforehand so I didn't have to spend significant time and money to prepare and travel to San Jose. The senior engineer who seemed a nice guy then gave me some advice on choosing the right career path that I really liked and appreciated but still it didn't make me less upset for wasting my time and money to go to a useless interview. I just wrote this to let you know that if you got direct onsite interview first of all do not get excited and then if you are not living in San Jose you might want to think twice before spending a lot of money to plan a trip.
