SSE Interview Prep
60 days. Four problems a day.One offer.
A daily plan we hand to engineers prepping for Senior Software Engineer loops. Each day pairs one DSA pattern with a Low-Level Design problem, a High-Level Design problem and a rotating tech focus — Java, concurrency, Kafka, Cassandra, Spring Boot, Docker, Kubernetes and more.
Share-friendly: every day has its own deep-link.
