Entrevista
Somebody described similar experience - didn't get professional feeling from interview process. Got a call from HR person, suffered through regular set of HR questions and was asked to take skill test. Same set of questions already described here - get missing letters and string animation. Not that difficult, especially given they let you pick a language, out of Java, c, c++ and more.
No feedback for a few weeks, then was told they passed. I guess I missed a punctuation somewhere :)

Pregunta 1
You are to write a method getMissingLetters, which takes a String, sentence, and returns all the letters it is missing (which prevent it from being a pangram)”
collection of particles is contained in a linear chamber. They all have the same speed, but some are headed toward the right and others are headed toward the left. These particles can pass through each other without disturbing the motion of the particles, so all the particles will leave the chamber relatively quickly.”
Opening the technical round, I was taken aback when they asked me to implement a thread-safe LRU cache, which I had just practiced on prachub.com during my prep. We spent a lot of time discussing different locking strategies, and I had to explain how to extend the cache for TTL-based eviction. It felt quite intense, and though I received an offer, I ultimately declined as the team dynamics didn’t seem like the right fit for me. The coding question was definitely a highlight, and I'm grateful for the targeted prep I had done.
First you have to do Hackerrank, which is doable but can be tricky. Then they like to screen your coding with leetcode like problems. After that, they start screening your design skills and general technical depth.

Had 3 rounds of Technical Interviews which I cleared easily. Recruiter told me that there would be few behavioral interviews once the headcount freeze would be lifted. It has been more than a year now and even after several follow-ups haven't received any response from the company. It also appears that I am not alone and there are many others who have cleared interviews but were kept on hold due to unavailability of headcount. 2S needs to stop wasting precious time of candidates if they do not intend to hire.
