Solicité el puesto a través de un captador. El proceso duró 4 semanas. Acudí a una entrevista en Hudson River Trading (New York, NY) en dic 2015
Entrevista
We had 3 phone interviews, They allowed me to schedule phone time through the web site by yourself. This is exceptional and very useful.
HRT has ventured into the subjects they are interested themselves and tried to figure out how deep a persons understanding is. While their emphasis was correct and very appealing to show their own strengths, it is quite hard to translate all required depth over the phone. Majority of the questions could be answered "that book" gives exact insight what you are looking for. They are looking for narrow specialists who invested their time deeply in single area and know it exactly, not for outliers who think on problems. They have not tried to figure out the candidate abilities over the phone.
Overall, level of the interviewers was good, it was pleasing and fun.

People are generally friendly. You should really know your stuff (networks, OS, algorithms) before you apply. I got bamboozled at the second round, but I learnt a lot from the interview process.

- Thread vs process, what's the difference? Talk about some common threading models.
-What are some methods of inter-process communication. Between threads. Between processes.
- Explain how a named pipe works (FIFO).
- What does the inline keyword do in C++? What are the pros and cons?
