Codility test post-mortem

Comments

I couldn't sleep. So I decide to write on post-mortem report on the Codility test.

Few tips for me when doing the test again:

  • I couldn't sleep after the test. My body is full of adrenaline. Thinking about the test: what went wrong, how to improve it, or wish I got more time. Since I am a morning person, I will do this kind of test in the morning in the future. So that I won't feel sleepy the next day.
  • I took too much time to the first task. Before the test begin, total of given minutes and number of tasks are mentioned. Get a countdown timer in the computer or physical kitchen timer and set it to total_minutes/total_tasks. So that I will be warm to move on to the next task.
  • I completed the tasks in wrong order. In future, I go through all the tasks and write step by step pseudo code on each task and test cases in order to make sure I understand the task completely. By doing that, I will also know roughly the order for completing the tasks and some ideas on ways to solve the tasks. I will have a better decision in the future.
  • When Submit this task button is click, it takes few seconds to go to the next tasks. I am not sure whether the timer does pause during that time. The best is submit the task at the very end. If the time is up, all the tasks will be submitted anyway.
  • Custom test cases does not accept as an expression. It gives me an error when ([i for i in xrange(3000)], 1) is given as a test case. I guess it has to be programming language neutral. So I write my test case as stdout (print statement) in the code editor instead. For example, print solution([i for i in xrange(3000)], 1) # 3.
  • Single uppercase character as a parameter is not very pythonic. I will change it to a descriptive lowercase parameter.

I guess the technical test is now web based. It is my first test. I got a feeling it won't be my last one. Although I didn't do well this time, I believe I will do better next time as experience counts.

Nowadays, technology is moving very fast. It is challenging to keep it up but I will never stop learning.

Kimchi

Kimchi, also spelled kimchee or gimchi, is a traditional fermented Korean side dish made of vegetables with a variety of seasonings. In traditional preparations, kimchi was stored underground in jars to keep cool and unfrozen during the winter months. There are hundreds of varieties of kimchi made with napa cabbage, radish, scallion, garlic, ginger or cucumber as the main ingredients.

Eclair

Comments

An éclair is an oblong pastry made with choux dough filled with a cream and topped with icing. The dough, which is the same as that used for profiterole, is typically piped into an oblong shape with a pastry bag and baked until it is crisp and hollow inside. Once cool, the pastry is then filled with a vanilla-, coffee- or chocolate-flavoured custard (crème pâtissière), or with whipped cream, or chiboust cream; and then iced with fondant icing. Other fillings include pistachio- and rum-flavoured custard, fruit-flavoured fillings, or chestnut purée. The icing is sometimes caramel, in which case the dessert may be called a bâton de Jacob.
