There are 4 rounds of interviews: HR screening, First User (Live Coding), Second User (System Design/Architecture), Manager (Culture Fit). All interview was smooth, but only after last round they told that the position has been filled for my level (they open the job ad as "All Level" and then may offer candidate based on the final whether they should hired in what level).

Couple of rounds of the interview, the first with HR, the rest with the engineers and managers. The whole process took approximately 2 months to complete from start to finish.
