I applied engineer position in Google Beijing. After a couple of days, got a call to setup the first round phone interview. The turn around time is really fast. Within a week, I got 3 phone interviews from them. I am now waiting the result. The interviews are all conducted in English, except the first one, the second half session is in Mandarin. I feel they are all oversea scholars base on their English fluency. The technical questions cover a very wide range, but are more focused on data manipulation, processing and storage. Google definitely has an interview questionnaire. They pick up from the set and ask. I didn't meet any tricky questions, but some questions are very academic.

因为开IMF World Bank会议, 果然是戒备森严啊. 平常从Marina Sqaure去Suntec Expo的那个过街天桥全都封了, 只能有通行证的过. 天桥底下Temasek Blvd全部封了, 架起隔离铁丝墙, 停着几辆防暴警车. 家乐福的那个入口站了两个荷枪实弹的士兵.大概想象了一下, 周围的高楼顶上肯定有狙击手盯着. Suntec一带的商店肯定生意受影响不小.

IMF and World Bank annual meeting will be held at Suntec Expo from Sep 10 to Sep 20. The streets around this area is closed since this Sunday 10PM. This morning I drove to work. Nice, so quite the streets near Suntec are. Lots of guys in uniform, police, civil defence, somehow I feel like VIP. There will be some protestors who are against finacial globalization during the meeting. IMF proposed to allow them protest outdoors. Singapore has refused. They can allow protest in the designated area indoors.
