Smartnumbers Software Engineer interview questions

Applying for junior/mid position via a recruiter. Initial screening call with a manager was very straightforward, motivations, past experiences etc. Second interview was just like the lead Developer review from 2017 (crazy they haven't changed their process by 2021, and this was for a mid-level position at most). 20 minutes to solve a problem that they spent 10 minutes explaining, and then instead of discussing the problem back and forth they refuse to clarify anything or talk about your solution until you're finished. 10 minutes to explain a problem in an interview is a big red flag for me, too much to process in too short a time. Employee explaining the problem kept jumping between parts of the problem which just confused the matter. This is a classic hypothetical interview problem, clear once you know the answer, shooting in the dark until them. They obviously have an answer in mind that they've spent 5years thinking about and any alternative is immediately void (no room to discuss as they are all muted once they hand over to you). Code your solution on a horrible drag+drop web based chart software (think gliffy/lucidcharts, typing pseudocode in text boxes, trying to draw lines with a mouse and generally awkward) Interview was virtual and was lots of feedback on the mic due to several interviewers all being in the same room on the same laptop with no headsets. Interview started 10mins late as well. Got a vibe of the software team being very business oriented as well. Overall incredibly dissapointing experience.
