This is first round interview. Give a self-introduction first. I feel like I did not say much enough. He then went over my resume and find an experience and ask me to tell something about it. I should have prepared 5 minutes' talk for each experience. He looked for the skill part, saw the computer network term and ask me what's the difference of Router and Switch. And what happens when we type an address in browser. I didn't know much about it. Learned that 5 years ago He ask if I have experience in Database, ask to write it down. I didn't do very well Then find the last 5 nodes of a link list. He wanna give me second chance and ask me about the Database again, I think I screwed it up....again.
