It took 4 months. 5 weeks of practicum, a really hard final case ( a DAO on Solana blockchain using anchor framework ). 2 technical interview even after these final cases. You can think of them as more than 2 because those included ETH, Solana and Frontend. After completing these steps, eventhough they told me the interview process was successful on my behalf they changed their mind about hiring a jr developer after 4 months.
