If you can spend quality 2-3 hours every day, you would need maybe a year to qualify for a junior position.
To pass an interview, you need to be able to
- talk on the subject for at least an hour straight
- show good communication skills
- ask relevant questions about their company (to show that you know how this industry operates)
- tell about your past achievements
- be likable on camera
Then do a test task quickly.
Then survive for 3 months with real tasks and real teammates, working for 12 hours every day on half the salary.
Then you got the job.
For the languages you mentioned there are hundreds of applicants for every open position.
