Question 1
they asked me about my experience and standard questions
I applied online. I interviewed at River in Dec 2025
Interview
Overall it was a very common setup:
- initial introductions
- past experiences overview
- short programming task
- marketing / product lineup
The first three were the usual stuff, nothing fancy. The programming task was a fun one: a simple interpreter for sequence of logical and mathematical operations, e.g. "OP_3 OP_2 OP_SUB OP_5 OP_ADD OP_5 OP_EQUAL". Operations/values would be read, parsed and executed in given order. Fun exercise. Discussed (too little time to actually implement) how the solution would evolve if brackets were introduced etc.
A surprise here was the last step, where there was no coding. The discussion was around estimating the number of online adds a person is exposed to over the course of a day.
In total, very enjoyable experience. People were all really nice and suppportive.
