A number of readers and visitors have written me to inquire about the infrequent updates to my blog these days. Well, I’ve been very busy at my full-time job, plus it’s difficult to access the Internet from work, so I can’t easily check my personal mail or update this blog during the workday. My 22-month-old son is also more and more demanding of my time at home — when he’s not busy passing all sorts of germs he picks up at daycare on to me and his mother.
I do have a bit of good news: my friend Xinfeng Zhou, a quant at Goldman Sachs, has written an excellent book on quant interview questions (lots of sample problems in math, stats, probability, brainteasers, programming, etc.). I acted as the editor of the book, and we expect it to be available on Amazon.com and other bookseller websites in the next few weeks. Please stay tuned. I’ll announce its availability when it’s published.
In the meantime, I’ll try to update this blog with fresh new sample questions as I can find the time. Please understand I try my best; it’s just my work and personal commitments make it hard to juggle too many things — and I sorely need to catch up on some sleep!
