Introduction
It is a good idea to celebrate 80 times mocking experience with a coding blog. What is the good topic? Julia learned a lot, and she likes to write common mistakes in the mocking experience.
Julia did some research on the topic "Do mocking make difference?". Julia likes to set a new goal for her practice, improve her communication.
One interesting topic Julia likes to bring up is 3000 algorithm practice, Julia likes to build up skills by playing hackerrank contest, Leetcode practice and mocking experience. And also Julia learns to journal her emotions through the practice in order to build mental toughness.
Julia started to cut short those long hours for Hackerrank contest, she likes to write a few blogs when she prepares to solve a medium or expert level algorithm, she also likes to read some good lecture notes and do some research on the topic, certainly Julia learns to succeed on week code of 33 and enjoyed her first gold medal.
Common mistakes
Julia was complained once that she made the mocking experience like an exam, it should be a conversation. And another time Julia was told that if she was given a hint, she should take it, do not be a hacker. Julia learns to respect the peer and follow the direction right away. So she was surprised that today mocking experience, she tried to give same advice, but the peer did not take it.
Here are 10 more mistakes Julia learns from her last 80 mocking experience:
1. One of the peers asked very politely in the first minute, how does the mocking work? Are you a professional? Question is how to show up very professionally? Age difference?
2. Prepare peer's algorithm very well as an interviewer. For example, quickly look up Google and get an API stackoverflow link for the peer.
3. Miss base cases in the algorithm analysis
4. Do not talk and explain the base case in DFS design in the first place. Need to learn more about DFS algorithm design, know different kinds of solutions, and then communicate efficiently.
5. Easy to get stuck or be distracted from the algorithm.
6. Fail to come out dynamic solution or recurrence formula quickly. Julia did notice the issue in her first round.
7. Some of peers expect the code ready to run with test cases and you should show the correct result.
Work hard until you can write the algorithm and make sure that the algorithm can run. Practice more.
The third time Julia wrote the same algorithm and then she was asked to run the code, she had a few bugs to fix.
8. Do not write code until you have fully figured out the algorithm. Explain the algorithm and share your thinking process. Julia had the mistake in one of her first 20 mocking practice.
9. Learn whiteboard testing. But test the code very hard. Do not fake it. Julia still found bugs by running the code using sample test case, after whiteboard testing. Do not fake the testing, work hard.
10. Prepare to extend the algorithm if the peer finish only first 10 minutes, try to extend the algorithm until the peer fails. Know how to measure the depth of the knowledge. Julia figured out after practicing more than 80 mocking practices.
11. Miss the optimal solution for an algorithm after more than 3 times practices. Julia knew the issue after 90 mocking practice.
12. There are always something new coming out in each mocking experience. Julia noticed that after she started third round.
Related work from Hackerrank contest
Julia likes to play tennis sports and play hackerrank contests. Both needs hard work.
Julia played over hundreds of hours tennis sports, hundreds of double and single matches, experienced the muscle pain and all kinds of issues, she also experienced a lot of joy through the hard work. She learns to control the ball and placement so well over thousands of strokes, she gains the new sports skills.
Related to tennis sports, from June 2016 to June 2017, Julia built up similar experience through Hackerrank contests, she journal every practice, wrote down her emotion, time to play, short term and long term goal, she started to collect 7 bronze medal, 2 silver medals, one gold medal last 12 months. Exactly after 12 month, she got her first gold medal, top 4% in ranking of over 11,000 players. She adapted her skills on tennis sports to competitive programming field.

Julia plays so many contests, there is always next one. No time to get frustrated long because she has to play next one and stay at the moment. It is hard to deal with frustration and expectation, but Julia learns to take care of herself with a lot of sports competition matches, just remind her that hard work beats the talent. Wishful thinking wastes time, but choose to sports therapy, learn from tennis professional players to work on basics.
Learn to count algorithms
It is not easy to stay humble for computer science Ph.D.
students. Julia worked on the computer science Ph.D. study from 2001 to 2010,
she never learned to count how many algorithms she works on. There is no
target, no goal setting on algorithm practice, and there is no result.
How does Julia happen to make changes after her full time
work last 7 years? Julia learned the tough lesson when she developed the sales
analysis report. She was challenged again and again about the number she
provided, she did not handle the pressure very well the first few years. From 2010 to 2015, Julia does not count how many algorithms she works on.
Starting from 2015, she put months hard work together to rewrite C# code with the new design, she likes to integrate with Microsoft Excel easily so she can continuously build some analysis.
Starting from 2015, she put months hard work together to rewrite C# code with the new design, she likes to integrate with Microsoft Excel easily so she can continuously build some analysis.
One day she sets a goal, she likes to be able to verify the final number in less than five minutes; she added the drill-down functionality in her
report, she can quickly export large data sets and use Microsoft Excel to do
further analysis to find root cause if need.
Be a top player in algorithm and data structure contest on
hackerrank, Julia also sets up a goal.
Her goal is to complete 3000 algorithm practice, enjoy the journey; she works on leetcode, meanwhile playing hackerrank contest; when she plays hackerrank contest, she uses Leetcode algorithms to help her to be a better player. She only completes over 100 algorithm related to Leetcode algorithm. Her gists shows 851 gists on June 29, 2017.
