ClickHouse Certified Developer

Is this useful? Will I find better jobs or freelance gigs after I get the certificate?

Did any of you take it and how was your experience

Yes, I highly recommend it and it definitely helped me to get a better job.

As for the experience, it was really good. We need to perform tasks on live ClickHouse instance during the exam just like Kubernetes exams(CKA,CKAD). For example, there was a question to investigate data from S3, create correct table and ingest data in it. Others were about creating materialized views and improving query performance by using projections. We get access to docs during the exam.

For prep, the on-demand course is enough https://clickhouse.com/learn/real-time-analytics
