Swiggy SDE-4 interview questions

Process had 6 telephonic rounds and 1 technical assignment. I find the process to be little unorganised. 1. My candidature was initially taken up for a team (which deals with developing services related to logisitcs optimisations) 2. I went through 5 telephonic rounds and 1 coding assignment. 3. I got a verbal acceptance on my candidature. 4. I wrote like 5 emails to enquire about my offer letter (and 3-5 email during before the verbal acceptance), but I never used to receive any response on the email. 5. Finally, I received a call from the HR that they have taken my candidature for the data platform team, and there will be 1 more call with data platform team manager. 6. Post that call, the offer which I had received was of SDE-3 and a compensation which was 20 percent less than my expectations which i stated explicitly before the process began. In short - they wasted my 1.5 months on this process.
