competitiveness: Pre-teen sprinter + HFT selectivity

I was a decent sprinter at age 6 through 13, then I realized I was not good enough to compete at Beijing municipal level.

There are quite a number of HFT shops in Singapore. I think they have a higher bar than ibanks. At ibank interviews I felt again like that pre-teen sprinter, but HFT interview is generally too hard for me

##Y c++IV improved much faster]U.S.than SG #insight{SCB breakthru

Hi XR,

I received 9 c++ offers since Mar 2017, mostly from U.S. In contrast, over the 4.5 years I spent in Singapore, I received only 3 c++ offers including a 90% offer from HFT firm WorldQuant (c++ job but not hardcore).

  1. Reason: buy-side employers — too picky. Most of the Singapore c++ jobs I tried are buy-side jobs. Many of the teams are not seriously hiring and only wanted rock stars.
    • In contrast, Since 2010 I tried about 6 Singapore ibank c++ jobs (Citi, Barclays, Macquarie, Standard Chartered Bank) and had much better technical wins than at buy-side interviews.
  2. Reason: Much fewer c++ jobs than in U.S.
  3. Reason: employee — I was always an employee while in Singapore and dare not attend frequent interviews.
  4. Reason: my c++ job in the U.S. are more mainstream so I had more opportunities to experiment on mainstream c++ interview topics. Experiments built up my confidence and depth.
  5. Reason: I had much more personal time to study and practice coding. This factor alone is not decisive. Without the real interviews, I would mostly waste my personal time.

Conclusion — availability of reasonable interview opportunities is a surprisingly oversize factor for my visible progress, 

By the way, Henry Wu (whom I told you about) had more successful c++ interviews. He joined WorldQuant and Bloomberg, two companies who didn’t take me up even after my technical wins.

IDE IV=easier4some !!4me

I guess many (majority ?) candidates consider IDE coding IV easier than white-board. I think they rely on IDE as a coding aid. Many programmers are not used to “demo” coding using white board … stressful, unnatural?

The “coding aid” feature helps me too, but it helps my competitors more !

If on white-board (or paper), my relative rating is A-, then on IDE i would score B

  • my relative weakness on IDE — ECT speed
  • my relative strength on white-board — clarity of thinking/explanation
