Albert Heijn interview questions

Applied at AH for position Senior Backend Developer (Kotlin/Java, Kafka). Had initial interview with HR where the main focus was on matching your skills to job requirement. Some of the optional skills like Kotlin didn't match my profile but I still got home test assignment. Decided to implement in Kotlin with a small experience in it. In couple of days received negative feedback with a picky comments. Apparently they were looking for a developer with solid Kotlin experience. Recently job description was updated to Kotlin only. I applied to a job with not accurate requirements and wasted time on home assignment. Very poor experience
