Lab49 (Budapest) reached out to me.
As it seemed I cannot join the company before a certain date we conveniently scheduled the 5 + 1 interviews in a 1.5-month period.
The communication was continuous and professional, I always got all the necessary information about the next step and other essential things.
I found the classmarker quiz and the codility test easy but there was also an online coding interview with advanced tasks.
I was comfortable with the stakeholder and executive interviews as well.
To sum it up, the whole process went smoothly and I felt myself good from the beginning till the end.
