d3View interview questions

The CEO asked me to go to their office. I drove for one and half hour to come over. After arriving to their company, the CEO gave me two projects to work on(both technologies of them are from my resume) and then left. After 3 hours, he told me I could go home to finish it and send him result. After sending him my result, he never relied to me. Actually, in his office, we just talked 10 minutes and he left me alone to finish projects. I drove 3 hours to commute.
