They will notify you by email about the start of the interviews. The dates are very immediate, so there is no time to study. However, the process is very friendly and enjoyable if you are not someone who stresses out quickly.

Very pleasant experience. The interviewers were very kind and patient. It is difficult to get into the company due to the large number of interested people. Study data structures and algorithms, and with that you will be more than ready.

Very difficult and many logic exercises, and it is very difficult to get in. I do not recommend. Little code required, problem-solving activities, many requests and few open positions.
