A hackerrank challenge with 2 days to complete. One question is lengthy and confusing but doable, that includes simple linear interpolation. The next is a tree one that has levels of size 1, 2, 3..., where you might want to understand triangle numbers. The final one is an interpolation/smoothing question where you have to fill in data points.
Interview questions [1]
Question 1
You have a tree with each level being 1, 2, 3... elements large. Each element has a value. Each parent has two children. Find the largest path down?
I applied online. The process took 4 weeks. I interviewed at Tibra (Sydney) in Aug 2024
Interview
Completely passed their coding OA, then got a generic behavioural assessment. I thought they were standard across the industry, but surprisingly, I was rejected without any further interview. Based on this experience, I am not sure they were even hiring.
I applied online. I interviewed at Tibra in Dec 2022
Interview
The process took 3+ months. The interviews are separated by 2 weeks each. Got rejected at the final stage after spending approx 40+ hours for interview preparation. Do not apply if you are not ready for rejection at any stage (the reviews of the company freaked me out a little - so perhaps a little relieved).
