Early background that helped get this job

His project was based on implementing a middleware library to support microtransactions in bitcoin, before serving ad-free content or any paid APIs.(Link to library:- https://github.com/getAlby/lsat-middleware)

He previously participated in many open source competitions such as Google Summer of codes and actively contributed to open source projects of the Linux Foundation. His open source contribution practices helped him crack the Summer of Bitcoin as well.

How to apply (application process)

After completing the Alby Wallet project, he started reaching out to various bitcoin-based open source startups on Twitter with his application and projects.

Structure of the interview/Rounds
1. Leader round
2. Technical round 1
3. Technical round 2

Leader round

The first round was a leader round where he was asked questions related to Bitcoin, blockchain and other related things about the Bitcoin wallet. This round was to make sure whether the interviewer is really interested in the Bitcoin community or not. So, firstly, their motive was to check how much a person knows about the community he will be working in, and then proceed with the next rounds. So if you are applying make sure you have good knowledge about this domain.

Technical round 1

The round started with a discussion about the project he did with Alby, focusing on both custodial and non-custodial wallets. In addition, there was a brief discussion of cryptography. After that, he was assigned a take-home task that involved implementing a simple blockchain API. The task required creating endpoints for mining blocks, adding transactions to the mempool, adding transactions to a block, and transaction validation, among other functions. Although there was no strict time limit, he submitted their solution (code with proper documentation and tests) the next day.

Technical round 2

This round was easier than the previous one, it started with a discussion about open source projects he contributed to in the past. The conversation then shifted to version control (Git) and associated commands. Furthermore, he was asked to run the Mercury wallet in dev mode on his machine, following the instructions outlined in the project’s ReadMe. In real time, he actively addressed and fixed several minor errors that occurred during this process.
