Select a table with multiple columns according to IN clause
If you don't need a column for each answer you can use group_concat() to build a single string with all answers per user.

drop table if exists survey_answer;
create table if not exists survey_answer(user int, question_id int, answer varchar(200));
insert into survey_answer values
(1,60,'answer 1'),
(1,61,'answer 2'),
(1,62,'answer 3'),
(2,61,'answer 4'),
(2,52,'answer 5'),
(3,40,'answer 6'),
(3,62,'answer 7'),
(4,61,'answer 8'),
(4,62,'answer 9'),
(4,10,'answer 10'),
(4,32,'answer 11');

select distinct(t1.user), 
       (select group_concat(t2.answer, ',')
        from survey_answer t2
        where t2.user = t1.user) answers
from survey_answer t1
;

drop table if exists survey_answer;


This is the result:

| user | answers                                   |
|------|-------------------------------------------|
| 1    | answer 1,,answer 2,,answer 3,             |
| 2    | answer 4,,answer 5,                       |
| 3    | answer 6,,answer 7,                       |
| 4    | answer 8,,answer 9,,answer 10,,answer 11, |
