Entrevista
Approached by a serviceTitan recruiter in LinkedIn.
R1: 30 mins phone interview with a lead recruiter.
R2: Hackerrank coding challenge(75mins). It was good. Easy problem.
R3: Pair programming session with Senior Manager(1.5 hours). Asked to design a Collection type. Difficulty type: Average
R4: Pair programming session with a Manager(1.5 hours). Problem was related to asynchronous programming with concurrecy level. It was average..solved it on time and then interviewer asked me to write the unit tests..no unit test frameworks are supported by the hackerrank. So I asked his expectations and the interviewer told me to test manually and he said, if he understands my test then its good. I wrote the tests and it passed..then he asked me to write a test to test the concurrency level..first I was stuck then few minutes later I proposed a POC..I also told him that I knew its a bad way to test but its just for testing, if the POC works then I will fix my tests. Fortunately POC works..then seems like he was happy..then he suggested me a different way to test that..it was a hint. I discussed with him about that approach he proposed and finally wrote the test as he wants..and it passed. We both were happy..then he talked with me 5 mins about the size of their teams and the tech stack they use. I thought it went well. But 4 days later, they sent me an email that I didn't pass the coding round.. nothing to say..waste of time..I think their recruiters might need to fix up some interview arrangements in each month, otherwise they will be out of work.

Pergunta 1
Weight based ranking.. Typical Linq problem..used select, orderby, and limit.
Difficulty level: Easy
90 min rounds - Glassdoor was helpful since they tend to repeat questions so check other reviews. After technical rounds, you math have a team match call with a hiring manager.

Interview process consisted of one HR phone screening followed by three technical rounds.
The technical rounds were:
Pair coding: implement a custom data structure.
Pair coding: parallel processing and async programming.
System design: data processing and AI-related architecture.
The first two technical rounds were conducted by one interviewer each. The exercises were medium difficulty or lower, and the interviewers were fair and clear.
The third round was supposed to have two interviewers, but only one joined the call. This felt awkward because the expectation had been set that two people would be present. I had also recently seen another Glassdoor review mentioning a similar situation, where one interviewer left during the interview, so this gave me the impression that something was off.
I asked at the end why the second interviewer had not joined, but the answer was not very convincing and no clear reason was provided. It would have been better if this had been explained at the beginning of the interview.
To be fair, I was not very familiar with the topic in the third round, and I do not think I performed well there. However, the missing interviewer made the experience feel disorganized and created the impression that the process may not have been fully structured or transparent.

Interview included 4 rounds, 1 with recruiter and 3 technical.
The first technical round was 1.5h pair programming session. The task was to implement a custom dictionary data structure. The complexity is medium or even below.
The second round also was 1.5h pair programming session and included parallel data processing using async/ await. The complexity was medium as well.
The third round was system design interview. The task was average as well, implement a system like Team City. On that round were present a Staff Dev and a Manager. The interview was 1.5h as well. In the very beginning the manager who were expected to lead the interview outlined the agenda: 1h of system design, 20 minutes for behavioral questions and 10 minutes for my questions. The interview started, they provided the task and I started asking questions about requirements, etc. and then designing. After approximately 10 minutes the manager disappeared. Just turned off his camera and microphone and I haven't seen him since. The staff dev didn't comment ghosting of his colleague and continued interviewing me. In fact, we were doing design all the session without any behavioral questions. In the end of the interview he said that I would receive the feedback by tomorrow evening. After 2 weeks the recruiter contacted me and said that they hired another person for that role.
