At beginning of the competition, you should do Exploratory Data Analysis, to find some relations in features and targets, write down some ideas for Feature Engineering from these explorations/insights, and much other stuff.
\nThe intermediate step, which also is one of the most important, is Metric Understanding. Choosing the right metric is crucial while evaluating machine learning (ML) models. Various metrics are proposed to evaluate ML models in different applications, and I thought it may be helpful to provide a summary of popular metrics here, for a better understanding of each metric and the applications they can be used for. In some applications looking at a single metric may not give you the whole picture of the problem you are solving, and you may want to use a subset of the metrics discussed in this post to have a concrete evaluation of your models.
\nThe most important step is to build a good model, that can well predict unseen data (aka Test Dataset), so choosing the right model is often not easy, it requires a lot of experiments and of course experience.
\nTaking some rest for no long time is very important so you keep your brain fresh and avoid burnout. Also, it is useful to spend this period of time with the benefit of learning some additional materials for certain competitions.
