I have been exactly in your situation when I worked at a Fintech firm back in India. Some of the similarities we had:

- Manager does a lot of coding
- There is no mentor/ teammate assigned to you for helping or pair programming with task
- No one expects any output from you in the sprint and are just busy doing their own work

I worked at this company for around a year and half and nothing good came out of it.

If your manager is doing coding most of the time, trust me that’s a very bad sign. A manager is supposed to spend most of their time doing managerial work and help you connect with teammates and ensuring that you get the right help to complete your tasks within that sprint, which includes ensuring that you are assigned tasks as well.

If you are new to the team and especially a new grad, a weekly 1:1 or atleast biweekly 1:1 with your manager and TL is crucial. If that’s not happening, not a good sign again.

- The repercussions of all this scenarios lead you to not learning in the long run. Teams like this keeps software engineer like this as a back up. Whenever they are faced with a hard pressing deadline project, they start bombarding you with task with no proper onboarding. If you are unable to finish tasks, you ultimately get managed out. I am really not trying to scare you here, but having worked exactly in a team like does more harm than good.

If I were in your shoes again, I would start doing the below steps:

1. If your goal is big tech/ startup, start applying to mid sized/ small companies first. The reason is, it would ensure that you are nullifying your failure rate fast and by the time you are applying to big tech/ companies you are already well seasoned with the interview patterns and your weaknesses. If you have a commute, start utilizing your commute time to apply to jobs. Use AI tools like [Simplified.com](http://Simplified.com) to fasten it up.
2. These days in interviews, they are expecting a candidate to know every detailed aspect of the project, even a new grad. If you are going to office, try to do some water cooler chats with some teammates and start asking them deep questions about projects.
3. For ex: why are we using this tech stack? Why this database? Why SQL vs noSQL ? How does our functionality work exactly ? Is it scalable ? How can we make it scalable ? See the stories on board which seem easy/ less story points even though not assigned to you. Start debugging on your own and see where you are stuck. Whenever the teammate who completed it raises a Pull request, try to have a casual conversation with them about understanding and thinking about it a certain way. Tell them they did an excellent job and start asking questions about how they did it the way they did. Trust me, people always love to talk about their work. This is how you build relations with teammates by paying attention to their work and asking good questions. Although, there is a fine line between asking questions and meddling with their work. I would try not to step on their shoes too much. In general, start having a conversation with your teammates about the project more in common hours. 
4. If it’s an existing project, what are the painpoints that team is currrently facing in terms of technicality ? I would pay really good attention to what teammates are saying and take good notes. These things come extremely handy for hiring manager interviews and behavioral interviews where they check your technical depth of project.
5. I understand you are extremely tired after your day job, but I would really suggest you start doing 1 leetcode problem a day atleast and utilize weekends to start brushing DS and Algo concepts.
6. Start utilizing your weekends to actively give mock interviews and address your weaknesses.
7. I agree market in general is really bad right now, especially for new grads and mid level engineers. It’s not entirely impossible though. I have been in market since last 3 months and managed to get something even being on a visa. If you put enough time and dedication, you will get through it.
8. Some final thoughts, I would not work in a company/ team like this for more than 4-5 months. I agree with Rahul, having reputed name like JPMC might start fetching you calls. Also, it takes up almost 2-3 months minimum to land a job offer once you start preparing. Utilize the free time you get at JPMC learning about teams tech stack and build small projects around that tech stack. This will help you answer questions in interview about tech stack.

Good luck to you and hope you find what you are looking for!
