Marqeta Sr. Software Engineer interview questions

Applied online, after a few days recruiter reached out to schedule the first phone screening. I provided some dates and times I would be available. After that, the recruiter just disappeared. I even sent another email to ask when I should expect a call, checked my spam folder too. It's been about 3 weeks now and still...nothing! They are not professional and I would not even bother applying here. I know it's the holiday season, but this does not excuse their lack of communication. I will not be moving forward with them even if I hear back now.

Recruiter reach out to me and had discussion about company, products and founder. Recruiter setup a technical coding challenge interview with Senior Engineer. I was able to complete coding challenge quickly. Senior Engineer asked another couple of question and he was not able to communicate clearly what he is asking. I reach out to recruiter for feedback after two weeks then recruiter schedule another technical interview with Team Lead. This time question is related to object oriented design. Interviewer type the question in hacker rank and went in silent mode. I hear keyboard press sound from other end. It seems his focus was not on me. I feel like one way communication. I was trying to clarify the question and Interviewer was not answering my clarification. I was keep telling this is my approach. Does it sound good to you. Interviewer was silent. I have completed the question and explain my approach and told couple of different approach to implement as well. At the end, Interviewer ask. Do you have any question. I asked what would be your approach to implement. Interviewer was not able to answer. Interview is two way process. Interviewer should talk to candidate and clarify the question. Interviewers should know what you want from candidate and how you let them perform their best.
