Just had a take home assessment with 5 questions and a dataset. Asked to get results for the complex questions using pandas. Some of the questions were complex but solvable. The last question was open ended asking about the tools we worked on

Same story as a lot of people here. Got asked to a coding exercise before talking to anyone. The assessment was trivial, but was vague as to what they were actually looking for. Received a rejection a day later with no feedback.
Highly recommend NOT applying here. Seems like a joke almost, and many people have the exact same experience.
This one was tough to read- thanks for taking the time to share your feedback. We'd love to hear more and are always looking to improve. Please email glassdoor@klaviyo.com if you'd like to get in touch.
