2019-12-16 – Mostly Software

New major version of coverage. sqlite storage, json report, contexts, relative filenames, dropped support for py 2.6/3.3/3.4.
Compiled new sbsc requirements and updated the banner.
Ordered a headset for the coding phone interviews where I need my hands to write.
Remember js spread operator or rest parameter: …obj
Played with coderpad to familiarize myself. Can write in many languages, set key bindings to vim, etc.
Webcammed practice interview, both tech and worklife questions. ~20m/350MB@720.
Placed grocery order with amazon (whole foods). Arrived a couple hours later.
Citadel tech test was moved to first week of Jan when the proctor is back from holiday.
Disney reached out for a senior software engineering position.

React/node/docker/mongo/k8s/aws/lambda.
Exciting projects. Thrown right in. Move teams quite a bit.
Almost all enter as contractors before full time. 50% insurance, no 401k. Paid hourly, but usually ~175k. No equity.
Shorter hours.
They’re an entertainment company before a tech company.
Just one 30m coding call, then onsites.

Bazel, c++, java. Lighter on python rules. Build and workspace files. Still similar to my old sx-setuptools, just files that take inputs and produce outputs. What files to build, what to do with it, etc.
Computers perform tasks. Humans should be solving problems.
Trees are just linked lists with multiple pointers, really. Graphs are just trees with no root.
DP is generically named. Just solve subproblems and cache/memoize.
C++ headers contain the declarations, source files use them.
Polymorphism. Two children inheriting the parent but using a method/attribute differently (e.g. parent animal with noise() method, child cat would noise(‘meow’) and dog would noise(‘bark’)).
let = block scoped. var = function scoped.
Lists and dicts are basically the only mutables in python. All the primitives are immutable.
Groovy is part of the java ecosystem.
Python > byte code (pyc) > machine code.
Netstat and wireshark.
Can think of websockets as just persistent http connections with a server over tcp/ip, where a socket is any general tcp/ip connection.
Every thread has its own stack (and registers), but all threads in the process share a heap.

A$ap and chance most of today.
Fed mouse.
Went through Amazon’s leadership principles and wrote examples of each: https://www.amazon.jobs/en/principles. Having gone through all, examples came readily. The principles were generic.
Received the online test for amazon. It takes 2 hours, and I can complete at any time in the next 2 weeks.

The coding portion is 90m, 2 explicit “write a function that returns this” questions.
I did a full demo test, finishing both after ~35min.
They use Aspiring Minds (not codepen or google docs). No proctor.
Asked Renee if it scores higher by submitting earlier, or if all extra time should be used improving/cleaning/commenting.
