Agoda Software Engineer interview questions

I applied for the position on their website and was contacted by the recruiter after 1 day. The recruiter told me that the role I applied for was filled already and suggested another role to me. The role was good for me so I proceeded with it. The recruiter was quick and scheduled my skype interview on the day after tomorrow with the development manager. The interview was of general/technical discussion type including topics such as threading, the output of code, what I know about Agoda and my interest interests. The following day, I received a "Take Home Test" involving threads and it was to be completed in 7 business days (10days). I submitted it on the 8th day (I worked on it for about 30hours). Five days after submission I received an email from the recruiter saying that I was still under consideration and give time until next week to give me the result of "Take Home Test". I quickly replied and after 45mins the recruiter emailed that the feedback was good and scheduled another Skype interview in the next week. This interview was with a Senior Software Engineer (Team Lead) and it was much more technical than the first one. Questions were related to load balancing and data structures. This time the got back to me after only 2 days and invited me to Bangkok for face to face interviews. The whole process of booking a ticket, getting a visa and then flying to Bangkok took me 25 days. I had a total 8 interviews in two days while I was in Bangkok. Most of the interviews were with development managers. Questions were mostly related to the algorithms such as sorting, searching and some of the questions were related to designing the system, I thought I did well in 5 of the interviews and in 3 I came up with only a partial solution (Evidently not, I didn't get an offer). I got rejection email after 2 working days and no feedback was provided. Overall, most of the interviewers were nice and spoke politely. However, I found two of them not interested and very serious(No jokes, no smile) and used a phone during the interview which I found little disrespecting (Maybe it is acceptable in their culture so could be just a bad judgement on my part). Strange things: 1. The office was very quiet when I went in for the interview. There were about 50 people in the room and it was quiet. 2. This is the strangest situation I have ever encountered (can be considered funny). Before the start of the interviews on the first day, I was waiting inside the office in front of the information desk and I asked the person behind the desk if I could use the restroom and they told me to wait and then went inside and came back after 5-10 mins and told me that I could use the restroom. I felt they went in to get a permission.

The experience is great and precious. There are a lot of problems solving questions which are rather interesting and a good revision as well but the company is focusing more on java specified.
