It's all good until founders understand that "we are just the help". They are the ones with the most risk, and they cannot simply walk away to a new job if they don't like how things are going.
But a lot of founders put too much weight on early employees, require working as much as the founder, or require to take responsibility in things that far outreach what they were accepting to when signing a contract.
This study, and some of the comments here that state the opposite are too generic. Whether communication or focus is more important depends on the nature of the product that someone most work on. Some projects require vast amount of communication, like working in a startup that's solving hard technical issues on greenfield R&D territory. But if you're working in a mobile dev shop and doing the Nth same iOS app for example, then probably you won't need to bounce ideas with co-workers but know exactly what you'll need to do, and it requires focus above all to finish it as soon as possible.
Of course most of the jobs are somewhere in between these extremes, but even in those cases the tasks usually alternate between the two.
Sadly this is true, even among software engineers and highly qualified people. You can still get a job without speaking Hungarian, and you'll be able to get through mandatory work stuff, but it may be uncomfortable during casual conversations. People often feel uneasy speaking English so they tend to switch to Hungarian if only one or two English speakers are in the group.
But if you can find a good community, then it may work out really well. Budapest is really affordable and SE salaries are very high compared to the average cost of living.
